For environmental concerns, these buildings must also be energy efficient. One component of these tasks is the provision of indoor air quality and thermal comfort, which can be enhanced with natural ventilation by the supply of fresh air. Working spaces can only be naturally ventilated with connections to the outdoors utilizing operable windows, double facades, ventilation stacks, balconies, patios, terraces and skygardens. Large amounts of fresh air can be provided to the indoor spaces without mechanical air-conditioning systems, which are widely employed in contemporary tall buildings. This paper tends to present the concept of natural ventilation for sustainable tall office buildings in order to achieve healthy and comfortable working spaces, as well as energy efficient environments. Initially the historical evolution of ventilation strategies for tall buildings is presented, beginning with natural ventilation and continuing with the introduction of mechanical air-conditioning systems. Then the emergence of natural ventilation due to the health and environmental concerns in tall buildings is handled, and the strategies for implementing this strategy are revealed. In the next section, a number of case studies that utilize this strategy are investigated. Finally, how tall office buildings can benefit from this strategy is discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tall%20office%20building" title="tall office building">tall office building</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=double-skin%20fa%C3%A7ade" title=" double-skin façade"> double-skin façade</a>, <a href="https://publications.waset.org/abstracts/search?q=stack%20ventilation" title=" stack ventilation"> stack ventilation</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20conditioning" title=" air conditioning"> air conditioning</a> </p> <a href="https://publications.waset.org/abstracts/12589/natural-ventilation-for-the-sustainable-tall-office-buildings-of-the-future" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12589.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">513</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4612</span> Derivation of Technology Element for Automation in Table Formwork in a Tall Building Construction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Junehyuck%20Lee">Junehyuck Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Dongmin%20Lee"> Dongmin Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hunhee%20Cho"> Hunhee Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyung-In%20Kang"> Kyung-In Kang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A table formwork method has recently been widely applied in reinforced concrete structures in a tall building construction to improve safety and productivity.

This is development of turbulent wake region behind an upstream building. The interaction with upstream building can produce significant changes in the response of the tall building. Here, in this paper, an attempt has been made to study wind induced interference effects on tall building. In order to study wind induced interference effect (IF) on Tall Building, initially a tall building (which is termed as Principal Building now on wards) with square plan shape has been considered with different Height to Width Ratio and total drag force is obtained considering different terrain conditions as well as different incident wind direction. Then total drag force on Principal Building is obtained by considering adjacent building which is termed as Interfering Building now on wards with different terrain conditions and incident wind angle. To execute study, Computational Fluid Dynamics (CFD) Code namely Fluent and Gambit have been used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title="computational fluid dynamics">computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=tall%20building" title=" tall building"> tall building</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulent" title=" turbulent"> turbulent</a>, <a href="https://publications.waset.org/abstracts/search?q=wake%20region" title=" wake region"> wake region</a>, <a href="https://publications.waset.org/abstracts/search?q=wind" title=" wind"> wind</a> </p> <a href="https://publications.waset.org/abstracts/6233/wind-interference-effect-on-tall-building" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6233.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">551</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4610</span> Wind Comfort and Safety of People in the Vicinity of Tall Buildings </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohan%20Kotamrazu">Mohan Kotamrazu </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tall buildings block and divert strong upper level winds to the ground. These high velocity winds many a time create adverse wind effects at ground level which can be uncomfortable and even compromise the safety of pedestrians and people who frequent the spaces in the vicinity of tall buildings. Discomfort can be experienced around the entrances and corners of tall buildings. Activities such as strolling or sitting in a park, waiting for a bus near a tall building can become highly unpleasant. For the elderly unpleasant conditions can also become dangerous leading to accidents and injuries. Today there is a growing concern among architects, planners and urban designers about the wind environment in the vicinity of tall building. Regulating authorities insist on wind tunnel testing of tall buildings in cities such as Wellington, Auckland, Boston, San Francisco, etc. prior to granting permission for their construction The present paper examines the different ways that tall buildings can induce strong winds at pedestrian level and their impact on people who frequent the spaces around tall buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tall%20buildings" title="tall buildings">tall buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20effects" title=" wind effects"> wind effects</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20comfort" title=" wind comfort"> wind comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20safety" title=" wind safety"> wind safety</a> </p> <a href="https://publications.waset.org/abstracts/45360/wind-comfort-and-safety-of-people-in-the-vicinity-of-tall-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45360.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">373</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4609</span> Compilation of Tall Building with Green Architecture Case Study: Babolsar City (North of Iran) at 2014-2015</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyyed%20Hossein%20Alavi">Seyyed Hossein Alavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Soudabeh%20Mehri%20Talarposhti"> Soudabeh Mehri Talarposhti </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Quick development of urban population need for housing on the one hand and prevention of irregular urban extension for optimum usage of urban land, resolving problems of urban physiognomy, land using, and environmental issues and urban transport, on the other hand, proposed tall building as urban area extension requirement in developing and advanced countries.

Various attempts were made by the government in overcoming problems of energy needs in Indonesia. In addition to the efforts of the government required the efforts made by the public to solve this problem. The concept of green building in the design of the building with efforts to use energy efficiently can be one of the efforts that can be applied to solve this problem. Jakarta is capital and the one of the major cities in Indonesia with high economic growth. This leads to increased demand for office space for the people. So that the construction of office buildings in big cities like Jakarta very numerous. Office building is one of the buildings that require large energy consumption. As a building that could potentially require huge amounts of energy, the design should consider the use of energy to help provide solutions to problems of energy crisis in Indonesia. The concept of energy efficient is one of the concepts addressed in an effort to use energy in buildings to save energy needs of the building operations. Therefore, it is necessary to have a study that explores the application of the concept of energy efficiency and conservation in office buildings in Jakarta. In this study using two (2) buildings case study that Sequis Center Building and Sampoerna Strategic Square. Both are office buildings in Jakarta have earned the Green Building Certificate of Green Building Council Indonesia (GBCI). The study used literature review methods to address issues raised earlier. Whether it's related to a literature review on the study of office buildings and green building. With this paper is expected to be obtained on the application of the concept of energy efficiency and conservation in office buildings that have earned recognition as a green building by GBCI. The result could be a reference to the architect in designing the next office buildings, especially related to the concept of energy use in buildings. From this study, it can be concluded that the concept of energy efficiency and conservation in the design of office buildings can be applied to its orientation, the openings, the use shade in buildings, vegetation and building material selection and efficient use of water. So that it can reduce energy requirements needed to meet the needs of the building user activity. So the concept of energy efficiency and conservation in office buildings can be one of the efforts to realize the Green Office Building. Recommendations from this study is that the design of office buildings should be able to apply the concept of energy utilization in the design office. This is to meet the energy needs of the office buildings in an effort to realize the Green Building. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20crisis" title="energy crisis">energy crisis</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20conservation" title=" energy conservation"> energy conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20building" title=" green building"> green building</a>, <a href="https://publications.waset.org/abstracts/search?q=office%20building" title=" office building"> office building</a> </p> <a href="https://publications.waset.org/abstracts/51904/implementation-of-efficiency-and-energy-conservation-concept-in-office-building-as-an-effort-to-achieve-green-office-building-case-studies-office-building-in-jakarta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51904.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">305</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4606</span> Optimum Design of Dual-Purpose Outriggers in Tall Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiwon%20Park">Jiwon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jihae%20Hur"> Jihae Hur</a>, <a href="https://publications.waset.org/abstracts/search?q=Kukjae%20Kim"> Kukjae Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hansoo%20Kim"> Hansoo Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, outriggers, which are horizontal structures connecting a building core to distant columns to increase the lateral stiffness of a tall building, are used to reduce differential axial shortening in a tall building. Therefore, the outriggers in tall buildings are used to serve the dual purposes of reducing the lateral displacement and reducing the differential axial shortening. Since the location of the outrigger greatly affects the effectiveness of the outrigger in terms of the lateral displacement at the top of the tall building and the maximum differential axial shortening, the optimum locations of the dual-purpose outriggers can be determined by an optimization method. Because the floors where the outriggers are installed are given as integer numbers, the conventional gradient-based optimization methods cannot be directly used. In this study, a piecewise quadratic interpolation method is used to resolve the integrality requirement posed by the optimum locations of the dual-purpose outriggers. The optimal solutions for the dual-purpose outriggers are searched by linear scalarization which is a popular method for multi-objective optimization problems. It was found that increasing the number of outriggers reduced the maximum lateral displacement and the maximum differential axial shortening. It was also noted that the optimum locations for reducing the lateral displacement and reducing the differential axial shortening were different.

This trend has recently brought out diverse building forms such as twisting tall buildings. This study investigates both the aerodynamic and design features of twisting tall buildings through comparative analyses. Since twisting a tall building give rise to additional complexities related with the form and structural system, lateral load effects become of greater importance on these buildings. The aim of this study is to analyze the inherent characteristics of these iconic forms by comparing the wind loads on twisting tall buildings with those on their prismatic twins. Through a case study research, aerodynamic analyses of an existing twisting tall building and its prismatic counterpart were performed and the results have been compared. The prismatic twin of the original building were generated by removing the progressive rotation of its floors with the same plan area and story height. Performance-based measures under investigation have been evaluated in conjunction with the architectural design. Aerodynamic effects have been analyzed by both wind tunnel tests and computational methods. High frequency base balance tests and pressure measurements on 3D models were performed to evaluate wind load effects on a global and local scale. Comparisons of flat and real surface models were conducted to further evaluate the effects of the twisting form without façade texture contribution. Comparisons highlighted that, the twisting form under investigation shows better aerodynamic behavior both for along wind but particularly for across wind direction. Compared to the prismatic counterpart; twisting model is superior on reducing vortex-shedding dynamic response by disorganizing the wind vortices. Consequently, despite the difficulties arisen from inherent complexity of twisted forms, they could still be feasible and viable with their attractive images in the realm of tall buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamic%20tests" title="aerodynamic tests">aerodynamic tests</a>, <a href="https://publications.waset.org/abstracts/search?q=motivation%20for%20twisting" title=" motivation for twisting"> motivation for twisting</a>, <a href="https://publications.waset.org/abstracts/search?q=tall%20buildings" title=" tall buildings"> tall buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=twisted%20forms" title=" twisted forms"> twisted forms</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20excitation" title=" wind excitation"> wind excitation</a> </p> <a href="https://publications.waset.org/abstracts/55996/investigation-of-aerodynamic-and-design-features-of-twisting-tall-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55996.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">234</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4604</span> Defining a Pathway to Zero Energy Building: A Case Study on Retrofitting an Old Office Building into a Net Zero Energy Building for Hot-Humid Climate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kwame%20B.%20O.%20Amoah">Kwame B.

An existing small office building in Melbourne, Florida, was chosen as a case study to integrate state-of-the-art design strategies and energy-efficient building systems to improve building performance and reduce energy consumption. The study aimed to explore possible ways to maximize energy savings and renewable energy generation sources to cover the building's remaining energy needs necessary to achieve net-zero energy goals. A series of retrofit options were reviewed and adopted with some significant additional decision considerations. Detailed processes and considerations leading to zero energy are well documented in this study, with lessons learned adequately outlined. Based on building energy simulations, multiple design considerations were investigated, such as emerging state-of-the-art technologies, material selection, improvements to the building envelope, optimization of the HVAC, lighting systems, and occupancy loads analysis, as well as the application of renewable energy sources. The comparative analysis of simulation results was used to determine how specific techniques led to energy saving and cost reductions. The research results indicate this small office building can meet net-zero energy use after appropriate design manipulations and renewable energy sources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title="energy consumption">energy consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20energy%20analysis" title=" building energy analysis"> building energy analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20retrofits" title=" energy retrofits"> energy retrofits</a>, <a href="https://publications.waset.org/abstracts/search?q=energy-efficiency" title=" energy-efficiency"> energy-efficiency</a> </p> <a href="https://publications.waset.org/abstracts/156385/defining-a-pathway-to-zero-energy-building-a-case-study-on-retrofitting-an-old-office-building-into-a-net-zero-energy-building-for-hot-humid-climate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156385.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">223</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4603</span> Comparing Occupants’ Satisfaction in LEED Certified Office Buildings and Non-LEED Certified Office Buildings: A Case Study of Office Buildings in Egypt and Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amgad%20A.%20Farghal">Amgad A.

The field studies were conducted in summer 2012. The measured environmental parameters in the four buildings were indoor air temperature, relative humidity, CO2 percentage and light intensity. The traditional building is located in Smart Village in Abu Rawash, Cairo, Egypt. The building was studied for 7 days resulting in 84 responds. The three rated buildings are in Istanbul; Turkey. A Platinum LEED certified office building is owned by BASF and gained a platinum certificate for new construction and major renovation. The building was studied for 3 days resulting in 13 responds. A Gold LEED certified office building is owned by BASF and gained a gold certificate for new construction and major renovation. The building was studied for 2 days resulting in 10 responds. A silver LEED certified office building is owned by Unilever and gained a silver certificate for commercial interiors. The building was studied for 7 days resulting in 84 responds. The results showed that all buildings had no significant difference regarding occupants’ satisfaction with the amount of lighting, noise level, odor and access to the outdoor view. There was significant difference between occupants’ satisfaction in LEED certified buildings and the traditional building regarding the thermal environment and the perception of the general environment (colors, carpet and decoration. The findings suggest that careful design could lead to a certified building that enhances the thermal environment and the perception of the indoor environment leading to energy consumption without scarifying occupants’ satisfaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title="energy consumption">energy consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=occupants%E2%80%99%20satisfaction" title=" occupants’ satisfaction"> occupants’ satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=rating%20systems" title=" rating systems"> rating systems</a>, <a href="https://publications.waset.org/abstracts/search?q=office%20buildings" title=" office buildings"> office buildings</a> </p> <a href="https://publications.waset.org/abstracts/10324/comparing-occupants-satisfaction-in-leed-certified-office-buildings-and-non-leed-certified-office-buildings-a-case-study-of-office-buildings-in-egypt-and-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10324.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">420</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4602</span> Measurement and Research of Green Office Building Operational Performance in China: A Case Study of a Green Office Building in Zhejiang Province</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xuechen%20Gui">Xuechen Gui</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian%20Ge"> Jian Ge</a>, <a href="https://publications.waset.org/abstracts/search?q=Senmiao%20Li"> Senmiao Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, green buildings in China have been developing rapidly and have developed into a wide variety of types, of which office building is a very important part. In many green office buildings, the energy consumption of building operation is high; the indoor environment quality needs to be improved, and the level of occupants’ satisfaction is low. This paper conducted a one-year measurement of operational performance of a green office building in Zhejiang Province. The measurement includes energy consumption of the building's one-year operation, the quality of the indoor environment and occupants’ satisfaction in different seasons. The energy consumption is collected from the power bureau. The quality of the indoor environment have been measured at different measuring points including offices, meeting rooms and reception for the whole year. The satisfaction of occupants are obtained from questionnaires. The results are compared with given standards and goals and the reasons why occupants are dissatisfied with the indoor environment are analyzed. Regarding energy consumption, the energy consumption of the building operational performance is much higher than the standard. Regarding the indoor environment, the temperature and humidity meet the standard for most of the time, but fine particulate matter (PM2.5) concentration is pretty high. Regarding occupants satisfaction, occupants have a higher expectation for indoor air quality even when the indoor air quality is well and occupants prefer a relatively humid environment. However the overall satisfaction is more than 80%, which indicates that occupants have a higher tolerability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20office%20building" title="green office building">green office building</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title=" energy consumption"> energy consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=indoor%20environment%20quality" title=" indoor environment quality"> indoor environment quality</a>, <a href="https://publications.waset.org/abstracts/search?q=occupants%20satisfaction" title=" occupants satisfaction"> occupants satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=operational%20performance" title=" operational performance"> operational performance</a> </p> <a href="https://publications.waset.org/abstracts/96621/measurement-and-research-of-green-office-building-operational-performance-in-china-a-case-study-of-a-green-office-building-in-zhejiang-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96621.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4601</span> Assessing Effectiveness of Outrigger and Belt Truss System for Tall Buildings under Wind Loadings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nirand%20Anunthanakul">Nirand Anunthanakul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is to investigate a 54-story reinforced concrete residential tall building structures—238.8 meters high.

Those advent stationary functions of tall building structures in metropolitan regions can be severely hazardous, in socio-economic terms, which also increase the requirement of advanced seismic performance. To achieve these progressive requirements, the seismic reinforcement for some old, conventional buildings have become enormously costly. The methods of increasing the buildings’ resilience against wind or earthquake loads have also become more advanced. Up to now, vibration control devices, such as the passive damper system, is still regarded as an effective and an easy-to-install option, in improving the seismic resilience of buildings at affordable prices. The main purpose of this paper is to examine 1) the optimization of the shape of visco plastic brace damper (VPBD) system which is one of hybrid damper system so that it can maximize its energy dissipation capacity in tall buildings against wind and earthquake. 2) the verification of the seismic performance of the visco plastic brace damper system in tall buildings; up to forty-storey high steel frame buildings, by comparing the results of Non-Linear Response History Analysis (NLRHA), with and without a damper system. The most significant contribution of this research is to introduce the optimized hybrid damper system that is adequate for high rise buildings. The efficiency of this visco plastic brace damper system and the advantages of its use in tall buildings can be verified since tall buildings tend to be affected by wind load at its normal state and also by earthquake load after yielding of steel plates. The modeling of the prototype tall building will be conducted using the Opensees software. Three types of modeling were used to verify the performance of the damper (MRF, MRF with visco-elastic, MRF with visco-plastic model) 22-set seismic records used and the scaling procedure was followed according to the FEMA code. It is shown that MRF with viscous, visco-elastic damper, it is superior effective to reduce inelastic deformation such as roof displacement, maximum story drift, roof velocity compared to the MRF only. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tall%20steel%20building" title="tall steel building">tall steel building</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20retrofit" title=" seismic retrofit"> seismic retrofit</a>, <a href="https://publications.waset.org/abstracts/search?q=viscous" title=" viscous"> viscous</a>, <a href="https://publications.waset.org/abstracts/search?q=viscoelastic%20damper" title=" viscoelastic damper"> viscoelastic damper</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20based%20design" title=" performance based design"> performance based design</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience%20based%20design" title=" resilience based design"> resilience based design</a> </p> <a href="https://publications.waset.org/abstracts/72375/seismic-retrofit-of-tall-building-structure-with-viscous-visco-elastic-visco-plastic-damper" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72375.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">193</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4599</span> Diagrid Structural System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Raghu">K.

In the late 19th century early designs of tall buildings recognized the effectiveness of diagonal bracing members in resisting lateral forces. Most of the structural systems deployed for early tall buildings were steel frames with diagonal bracings of various configurations such as X, K, and eccentric. Though the historical research a filtering concept is developed original and remedial technology- through which one can clearly understand inter-relationship between the technical evolution and architectural esthetic and further stylistic transition buildings. Diagonalized grid structures – “diagrids” - have emerged as one of the most innovative and adaptable approaches to structuring buildings in this millennium. Variations of the diagrid system have evolved to the point of making its use non-exclusive to the tall building. Diagrid construction is also to be found in a range of innovative mid-rise steel projects. Contemporary design practice of tall buildings is reviewed and design guidelines are provided for new design trends. Investigated in depths are the behavioral characteristics and design methodology for diagrids structures, which emerge as a new direction in the design of tall buildings with their powerful structural rationale and symbolic architectural expression. Moreover, new technologies for tall building structures and facades are developed for performance enhancement through design integration, and their architectural potentials are explored. By considering the above data the analysis and design of 40-100 storey diagrids steel buildings is carried out using E-TABS software with diagrids of various angle to be found for entire building which will be helpful to reduce the steel requirement for the structure. The present project will have to undertake wind analysis, seismic analysis for lateral loads acting on the structure due to wind loads, earthquake loads, gravity loads. All structural members are designed as per IS 800-2007 considering all load combination. Comparison of results in terms of time period, top storey displacement and inter-storey drift to be carried out. The secondary effect like temperature variations are not considered in the design assuming small variation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diagrid" title="diagrid">diagrid</a>, <a href="https://publications.waset.org/abstracts/search?q=bracings" title=" bracings"> bracings</a>, <a href="https://publications.waset.org/abstracts/search?q=structural" title=" structural"> structural</a>, <a href="https://publications.waset.org/abstracts/search?q=building" title=" building"> building</a> </p> <a href="https://publications.waset.org/abstracts/17351/diagrid-structural-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17351.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">386</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4598</span> Reduction of Differential Column Shortening in Tall Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hansoo%20Kim">Hansoo Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Seunghak%20Shin"> Seunghak Shin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The differential column shortening in tall buildings can be reduced by improving material and structural characteristics of the structural systems.

The rigidly connected horizontal members including outriggers reduce the differential shortening between adjacent vertical members. The axial stiffness of columns with greater shortening can be effectively increased by placing additional reinforcement at the columns, thus the differential column shortening can be reduced in the design stage.

It provides a different mode for dealing with sustainability in tall architecture, taking into consideration the speciality of its typology. To this end, the article develops a Biomimetic Structural Form as a paradigm to attain Vital Sustainability. A Biomimetic Structural Form, which is derived from the amalgamation of biomimicry as an approach for sustainability defining nature as source of knowledge and inspiration in solving humans’ problems and a Structural Form as a catalyst for evolving tall architecture, is a dynamic paradigm emerging from a conceptualizing and morphological process. A Biomimetic Structural Form is a flow system whose different forces and functions tend to be “better”, more "fit", to “survive”, and to be efficient. Through geometry and function—the two aspects of knowledge extracted from nature—the attributes of the Biomimetic Structural Form are formulated. Vital Sustainability is the survival level of sustainability in natural systems through which a system enhances the performance of its internal working and its interaction with the external environment. A Biomimetic Structural Form, in this context, is a medium for evolving tall architecture to emulate natural models in their ways of coexistence with the environment. As an integral part of this article, the sustainable super tall building 3Ts is discussed as a case study of applying Biomimetic Structural Form.    <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomimicry" title="biomimicry">biomimicry</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20in%20nature" title=" design in nature"> design in nature</a>, <a href="https://publications.waset.org/abstracts/search?q=high-rise%20buildings" title=" high-rise buildings"> high-rise buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20form" title=" structural form"> structural form</a>, <a href="https://publications.waset.org/abstracts/search?q=tall%20architecture" title=" tall architecture"> tall architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=vital%20sustainability" title=" vital sustainability"> vital sustainability</a> </p> <a href="https://publications.waset.org/abstracts/64968/a-biomimetic-structural-form-developing-a-paradigm-to-attain-vital-sustainability-in-tall-architecture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64968.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">312</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4596</span> Post Occupancy Evaluation of the Green Office Building with Different Air-Conditioning Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ziwei%20Huang">Ziwei Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian%20Ge"> Jian Ge</a>, <a href="https://publications.waset.org/abstracts/search?q=Jie%20Shen"> Jie Shen</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiantao%20Weng"> Jiantao Weng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Retrofitting of existing buildings plays a critical role to achieve sustainable development. This is being considered as one of the approaches to achieving sustainability in the built environment. In order to evaluate the different air-conditioning systems effectiveness and user satisfaction of the existing building which had transformed into green building effectively and accurately. This article takes the green office building in Zhejiang province, China as an example, analyzing the energy consumption, occupant satisfaction and indoor environment quality (IEQ) from the perspective of the thermal environment. This building is special because it combines ground source heat pump system and Variable Refrigerant Flow (VRF) air-conditioning system. Results showed that the ground source heat pump system(EUIa≈25.6) consumes more energy than VRF(EUIb≈23.8). In terms of a satisfaction survey, the use of the VRF air-conditioning was more satisfactory in temperature. However, the ground source heat pump is more satisfied in air quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=post-occupancy%20evaluation" title="post-occupancy evaluation">post-occupancy evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20office%20building" title=" green office building"> green office building</a>, <a href="https://publications.waset.org/abstracts/search?q=air-conditioning%20systems" title=" air-conditioning systems"> air-conditioning systems</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20source%20heat%20pump%20system" title=" ground source heat pump system"> ground source heat pump system</a> </p> <a href="https://publications.waset.org/abstracts/88345/post-occupancy-evaluation-of-the-green-office-building-with-different-air-conditioning-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88345.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">196</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4595</span> Barclays Bank Zambia: Considerations for Raft Foundation Design on Dolomite Land</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yashved%20Serhun">Yashved Serhun</a>, <a href="https://publications.waset.org/abstracts/search?q=Kim%20A.%20Timm"> Kim A.

A unique characteristic of the development is that the building footprint is positioned on dolomitic land. Dolomite rock has the tendency to react with and breakdown in the presence of slightly acidic water, including rainwater. This leads to a potential for subsidence and sinkhole formation. Subsidence and the formation of sinkholes beneath a building can be detrimental during both the construction and operational phases. This paper outlines engineering principles which were considered during the structural design of the raft foundation for the Barclays head office building. In addition, this paper includes multidisciplinary considerations and the impact of these on the structural engineering design of the raft foundation. By ensuring that the design of raft foundations on dolomitic land incorporates the requirements of all disciplines and relevant design codes during the design process, the risk associated with subsidence and sinkhole formation can be effectively mitigated during the operational phase of the building. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dolomite" title="dolomite">dolomite</a>, <a href="https://publications.waset.org/abstracts/search?q=dolomitic%20land" title=" dolomitic land"> dolomitic land</a>, <a href="https://publications.waset.org/abstracts/search?q=raft%20foundation" title=" raft foundation"> raft foundation</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20engineering%20design" title=" structural engineering design"> structural engineering design</a> </p> <a href="https://publications.waset.org/abstracts/108648/barclays-bank-zambia-considerations-for-raft-foundation-design-on-dolomite-land" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108648.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">124</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4594</span> Architectural Identity in Manifestation of Tall-buildings' Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huda%20Arshadlamphon">Huda Arshadlamphon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Advancing frontiers of technology and industry is moving rapidly fast influenced by the economic and political phenomena. One vital phenomenon,which has had consolidated the world to a one single village, is Globalization. In response, architecture and the built-environment have faced numerous changes, adjustments, and developments. Tall-buildings, as a product of globalization, represent prestigious icons, symbols, and landmarks for highly economics and advanced countries. Despite the fact, this trend has been encountering several design challenges incorporating architectural identity, traditions, and characteristics that enhance the built-environments' sociocultural values and traditions. The necessity of these values and traditionsform self-solitarily, leading to visual and spatial creativity, independency, and individuality. In other words, they maintain the inherited identity and avoid replications in all means and aspects. This paper, firstly, defines globalization phenomenon, architectural identity, and the concerns of sociocultural values in relation to the traditional characteristics of the built-environment. Secondly, through three case-studies of tall-buildings located in Jeddah city, Saudi Arabia, the Queen's Building, the National Commercial Bank Building (NCB), and the Islamic Development Bank Building; design strategies and methodologies in acclimating architectural identity and characteristics in tall-buildings are discussed. The case-studies highlight buildings' sites and surroundings, concepts and inspirations, design elements, architectural forms and compositions, characteristics, issues, barriers, and trammels facing the designs' decisions, representation of facades, and selection of materials and colors. Furthermore, the research will elucidate briefs of the dominant factors that shape the architectural identity of Jeddah city. In conclusion, the study manifests four tall-buildings' design standards guideline in preserving and developing architectural identity in Jeddah city; the scale of urban and natural environment, the scale of architectural design elements, the integration of visual images, and the creation of spatial scenes and scenarios. The prosed guideline will encourage the development of architectural identity aligned with zeitgeist demands and requirements, supports the contemporary architectural movement toward tall-buildings, and shoresself-solitarily in representing sociocultural values and traditions of the built-environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=architectural%20identity" title="architectural identity">architectural identity</a>, <a href="https://publications.waset.org/abstracts/search?q=built-environment" title=" built-environment"> built-environment</a>, <a href="https://publications.waset.org/abstracts/search?q=globalization" title=" globalization"> globalization</a>, <a href="https://publications.waset.org/abstracts/search?q=sociocultural%20values%20and%20traditions" title=" sociocultural values and traditions"> sociocultural values and traditions</a>, <a href="https://publications.waset.org/abstracts/search?q=tall-buildings" title=" tall-buildings"> tall-buildings</a> </p> <a href="https://publications.waset.org/abstracts/147184/architectural-identity-in-manifestation-of-tall-buildings-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147184.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">163</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4593</span> Thermal Comfort in Office Rooms in a Historic Building with Modernized Heating, Ventilation and Air Conditioning Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Bakhtiari">Hossein Bakhtiari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathias%20Cehlin"> Mathias Cehlin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Akander"> Jan Akander</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Envelopes with low thermal performance is a common characteristic in many European historic buildings which leads to higher energy demand for heating and cooling as well as insufficient thermal comfort for the occupants. This paper presents the results of a study on the thermal comfort in the City Hall (Rådhuset) in Gävle, Sweden. This historic building is currently used as an office building. It is equipped with two relatively modern mechanical heat recovery ventilation systems with displacement ventilation supply devices in the offices. The district heating network heats the building via pre-heat supply air and radiators. Summer cooling comes from an electric heat pump that rejects heat into the exhaust ventilation air. A building management system controls HVAC equipment (heating, ventilation and air conditioning). The methodology is based on on-site measurements, data logging on the management system and evaluating the occupants’ perception of a summer and a winter period indoor environment using a standardized questionnaire. The main aim of the study is to investigate whether or not it is enough to have modernized HVAC systems to get adequate thermal comfort in a historic building with poor envelope performance used as an office building in Nordic climate conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=historic%20buildings" title="historic buildings">historic buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=on-site%20measurements" title=" on-site measurements"> on-site measurements</a>, <a href="https://publications.waset.org/abstracts/search?q=standardized%20questionnaire" title=" standardized questionnaire"> standardized questionnaire</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20comfort" title=" thermal comfort"> thermal comfort</a> </p> <a href="https://publications.waset.org/abstracts/69456/thermal-comfort-in-office-rooms-in-a-historic-building-with-modernized-heating-ventilation-and-air-conditioning-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69456.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">374</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4592</span> Prediction of Fire Growth of the Office by Real-Scale Fire Experiment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kweon%20Oh-Sang">Kweon Oh-Sang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kim%20Heung-Youl"> Kim Heung-Youl</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Estimating the engineering properties of fires is important to be prepared for the complex and various fire risks of large-scale structures such as super-tall buildings, large stadiums, and multi-purpose structures.

There is an ongoing trend in designing office buildings with a high proportion of glazing which relatively increases the risk of high visual discomfort. Providing a more realistic lighting analysis can be of high value at the early stages of building design when necessary changes can be made at a very low cost. This holistic approach can be achieved by incorporating subjective evaluation and user behaviour in computer simulation and provide a comprehensive lighting analysis. In this research, a detailed computer simulation model has been made using Radiance and Daysim. Afterwards, this model was validated by measurements and user feedback. The case study building is the school of science at Griffith University, Gold Coast, Queensland, which features highly glazed office spaces. In this paper, the visual comfort predicted by the model is compared with a preliminary survey of the building users to evaluate how user behaviour such as desk position, orientation selection, and user movement caused by daylight changes and other visual variations can inform perceptions of visual comfort. This work supports preliminary design analysis of visual comfort incorporating the effects of gaze shift patterns and views with the goal of designing effective layout for office spaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lighting%20simulation" title="lighting simulation">lighting simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=office%20buildings" title=" office buildings"> office buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20behaviour" title=" user behaviour"> user behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=validation" title=" validation"> validation</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20comfort" title=" visual comfort"> visual comfort</a> </p> <a href="https://publications.waset.org/abstracts/81677/highly-glazed-office-spaces-simulated-visual-comfort-vs-real-user-experiences" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81677.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">213</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4590</span> On the Stability Exact Analysis of Tall Buildings with Outrigger System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahrooz%20Abed">Mahrooz Abed</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20R.%20Masoodi"> Amir R.

Some efficient structures for drift control and base moment reduction in tall buildings is outrigger and belt truss systems. When adopting outrigger beams in building design, their location should be in an optimum position for an economical design. A range of different strategies has been employed to identify the optimum locations of these outrigger beams under wind load. However, there is an absence of scientific research or case studies dealing with optimum outrigger location using buckling analysis. In this paper, one outrigger system is considered at the middle of height of structure. The optimum location of outrigger will be found based on the buckling load limitation. The core of structure is modeled by a clamped tapered beam. The exact stiffness matrix of tapered beam is formulated based on the Euler-Bernoulli theory. Finally, based on the buckling load of structure, the optimal location of outrigger will be found. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tall%20buildings" title="tall buildings">tall buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=outrigger%20system" title=" outrigger system"> outrigger system</a>, <a href="https://publications.waset.org/abstracts/search?q=buckling%20load" title=" buckling load"> buckling load</a>, <a href="https://publications.waset.org/abstracts/search?q=second-order%20effects" title=" second-order effects"> second-order effects</a>, <a href="https://publications.waset.org/abstracts/search?q=Euler-Bernoulli%20beam%20theory" title=" Euler-Bernoulli beam theory"> Euler-Bernoulli beam theory</a> </p> <a href="https://publications.waset.org/abstracts/34858/on-the-stability-exact-analysis-of-tall-buildings-with-outrigger-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34858.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">396</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4589</span> Estimation of Seismic Deformation Demands of Tall Buildings with Symmetric Setbacks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Alirezaei">Amir Alirezaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahram%20Vahdani"> Shahram Vahdani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study estimates the seismic demands of tall buildings with central symmetric setbacks by using nonlinear time history analysis. Three setback structures, all 60-story high with setback in three levels, are used for evaluation. The effects of irregularities occurred by setback, are evaluated by determination of global-drift, story-displacement and story drift. Story-displacement is modified by roof displacement and first story displacement and story drift is modified by global drift. All results are calculated at the center of mass and in x and y direction. Also the absolute values of these quantities are determined. The results show that increasing of vertical irregularities increases the global drift of the structure and enlarges the deformations in the height of the structure. It is also observed that the effects of geometry irregularity in the seismic deformations of setback structures are higher than those of mass irregularity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deformation%20demand" title="deformation demand">deformation demand</a>, <a href="https://publications.waset.org/abstracts/search?q=drift" title=" drift"> drift</a>, <a href="https://publications.waset.org/abstracts/search?q=setback" title=" setback"> setback</a>, <a href="https://publications.waset.org/abstracts/search?q=tall%20building" title=" tall building"> tall building</a> </p> <a href="https://publications.waset.org/abstracts/22134/estimation-of-seismic-deformation-demands-of-tall-buildings-with-symmetric-setbacks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22134.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">424</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4588</span> Architectural and Structural Analysis of Selected Tall Buildings in Warsaw, Poland</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Szolomicki">J.

When analyzing the architecture of Warsaw, it can be concluded that it is currently a rapidly growing city with technologically advanced skyscrapers that belong to the category of intelligent buildings. The constructional boom over the last dozen years has seen the erection of postmodern skyscrapers for office and residential use. This article focuses on how Warsaw has recently joined the most architecturally interesting cities in Europe. Warsaw is currently in fifth place in Europe in terms of the number of skyscrapers and is considered the second most preferred city in Europe (after London) for investment related to them.

Therefore, a low-cost facility management program (FMP) should be used to provide a satisfactory built environment for these occupants. Facility management (FM) has been recently used in building projects as a critical task. It has been effective in reducing operation and maintenance cost of these facilities. Issues of information integration and visualization capabilities are critical for reducing the complexity and cost of FM. Building information modeling (BIM) can be used as a strong visual modeling tool and database in FM. The main objective of this study is to examine the applicability of BIM in the FM process during a building’s operational phase. For this purpose, a seven-storey office building is modeled Autodesk Revit software. Authors integrated the cloud-based environment using a visual programming tool, Dynamo, for the purpose of having a real-time cloud-based communication between the facility managers and the participants involved in the project. An appropriate and effective integrated data source and visual model such as BIM can reduce a building’s operational and maintenance costs by managing the building life cycle properly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20information%20modeling" title="building information modeling">building information modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=facility%20management" title=" facility management"> facility management</a>, <a href="https://publications.waset.org/abstracts/search?q=operational%20phase" title=" operational phase"> operational phase</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20life%20cycle" title=" building life cycle"> building life cycle</a> </p> <a href="https://publications.waset.org/abstracts/108963/integrating-building-information-modeling-into-facilities-management-operations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108963.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">154</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4586</span> Indoor Environment Quality and Occupant Resilience Toward Climate Change: A Case Study from Gold Coast, Australia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soheil%20Roumi">Soheil Roumi</a>, <a href="https://publications.waset.org/abstracts/search?q=Fan%20Zhang"> Fan Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Rodney%20Stewart"> Rodney Stewart</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indoor environmental quality (IEQ) indexes represented the suitability of a place to study, work, and live.

However, increasing the height of a building leads to an increase in structural material corresponding to the loads imposed by lateral loads. Based on this approach, new structural systems are emerging to provide strength and stiffness with the minimum premium for height. In this research, selected tube-type structural systems such as framed tubes, braced tubes, diagrids and hexagrid systems were applied as a single tube, tubular structures combined with braced core and outrigger trusses on a set of 48, 72, and 96-story, respectively, to improve integrated structural systems. This paper investigated structural material consumption by model structures focusing on the premium for height. Compared analytical results indicated that as the height of the building increased, combination of the structural systems caused the framed tube, hexagrid and braced tube system to pay fewer premiums to material tonnage while in diagrid system, combining the structural system reduced insignificantly the steel material consumption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=braced%20tube" title="braced tube">braced tube</a>, <a href="https://publications.waset.org/abstracts/search?q=diagrid" title=" diagrid"> diagrid</a>, <a href="https://publications.waset.org/abstracts/search?q=framed%20tube" title=" framed tube"> framed tube</a>, <a href="https://publications.waset.org/abstracts/search?q=hexagrid" title=" hexagrid"> hexagrid</a> </p> <a href="https://publications.waset.org/abstracts/88416/optimum-design-of-tall-tube-type-building-an-approach-to-structural-height-premium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88416.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">289</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4584</span> An Investigation on the Effect of Window Tinting on Thermal Comfort inside Office Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20El-Azzeh">S.

If this study was ignored, problems will start to occur for the occupants in the future. In hot climates, where solar radiations are entering buildings all year long, occupant’s thermal comfort in office buildings needs to be examined. This study aims to investigate the thermal comfort at an existing office building at the Australian College of Kuwait and test its validity and improve occupant’s thermal satisfaction by covering windows with a heat rejection tint material that enables sunlight to pass through the office while reflecting solar heat outside. Environmental variables were measured using thermal comfort data logger INNOVA 1221 to find the predicted mean vote (PMV) in the selected location. Also, subjective variables were measured to find the actual mean vote (AMV) through surveys distributed among occupants in the selected case study office. All the variables collected were analyzed and classified according to international standards ISO 7730 and ASHRAE55. The results of this study showed improvement in both PMV and AMV. The mean value of PMV based on the original design was 0.691 which dropped to 0.32 after installation and it still at comfort zone. Also, the mean value of the AMV has improved for the first occupant, where before it was -0.46 and it became -1 which is cooler. For the other occupant, it was slightly warm with a mean value of 0.9 and it was improved and became cooler with a -0.25 mean value based on American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) seven-point scale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermal%20comfort" title="thermal
