Specifically, a masonry brick wall and a light-steel framed (LSF) wall with comparable insulation performance are analyzed. A Monte Carlo technique, employing Latin Hypercube Sampling (LHS), is utilized to quantify uncertainties and determine the probability of failure for both walls exposed to standard and parametric fires, following ISO 834 and Eurocodes guidelines. Results show that the probability of failure for the brick masonry wall under standard fire exposure is estimated at 4.8%, while the LSF wall is 7.6%. These probabilities decrease to 0.4% and 4.8%, respectively, when subjected to parametric fires. Notably, the complex LSF wall exhibits higher variability in predicting time to failure for specific criteria compared to the less complex brick wall, especially at higher temperatures. The proposed approach highlights the need for Probabilistic Risk Assessment (PRA) to accurately evaluate the reliability and safety levels of complex designs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20complexity" title="design complexity">design complexity</a>, <a href="https://publications.waset.org/abstracts/search?q=probability%20of%20failure" title=" probability of failure"> probability of failure</a>, <a href="https://publications.waset.org/abstracts/search?q=monte%20carlo%20analysis" title=" monte carlo analysis"> monte carlo analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=compartmentation%20walls" title=" compartmentation walls"> compartmentation walls</a>, <a href="https://publications.waset.org/abstracts/search?q=insulation" title=" insulation"> insulation</a> </p> <a href="https://publications.waset.org/abstracts/170851/the-influence-of-design-complexity-of-a-building-structure-on-the-expected-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170851.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">71</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">4843</span> Improving Carbon Fiber Structural Battery Performance with Polymer Interface</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kathleen%20Moyer">Kathleen Moyer</a>, <a href="https://publications.waset.org/abstracts/search?q=Nora%20Ait%20Boucherbil"> Nora Ait Boucherbil</a>, <a href="https://publications.waset.org/abstracts/search?q=Murtaza%20Zohair"> Murtaza Zohair</a>, <a href="https://publications.waset.org/abstracts/search?q=Janna%20Eaves-Rathert"> Janna Eaves-Rathert</a>, <a href="https://publications.waset.org/abstracts/search?q=Cary%20Pint"> Cary Pint</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study demonstrates the significance of interface engineering in the field of structural energy by being the first case where the performance of the system with the structural battery is greater than the performance of the same system with a battery separate from the system. The benefits of improving the interface in the structural battery were tested by creating carbon fiber composite batteries (and independent graphite electrodes and lithium iron phosphate electrodes) with and without an improved interface. Mechanical data on the structural batteries were collected using tensile tests and electrochemical data was collected using scanning electron microscopy equipment. The full-cell lithium-ion structural batteries had capacity retention of over 80% exceeding 100 cycles with an average energy density of 52 W h kg−1 and a maximum energy density of 58 W h kg−1. Most scientific developments in the field of structural energy have been done with supercapacitors. Most scientific developments with structural batteries have been done where batteries are simply incorporated into the structural element. That method has limited advantages and can create mechanical disadvantages. This study aims to show that a large improvement in structure energy research can be made by improving the interface between the structural device and the battery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20materials" title="composite materials">composite materials</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20performance" title=" electrochemical performance"> electrochemical performance</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20interface" title=" polymer interface"> polymer interface</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20batteries" title=" structural batteries"> structural batteries</a> </p> <a href="https://publications.waset.org/abstracts/153279/improving-carbon-fiber-structural-battery-performance-with-polymer-interface" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153279.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">114</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">4842</span> Building Bridges on Roads With Major Constructions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Zaidour">Mohamed Zaidour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this summary, we are going to look in brief at the bridges and their building and construction on most roads and we have followed a simple method to explain each field clearly because the geographical and climatic diversity of an area leads to different methods and types of roads and installation engineering in other areas In mountain areas we need to build retaining walls in areas of rain.

To mitigate the impact of these seismic events, it is crucial to identify and thoroughly assess the vulnerability of buildings and infrastructure, ensuring their safety through principled reinforcement. By adopting new methods of risk assessment, we can effectively reduce the potential risks associated with future earthquakes. In our research, we have observed that the coefficient of behavior in the fourth chapter is 1.65 for the initial structure and 1.72 for the Superframe structure. This indicates that the Superframe structure can enhance the strength of the main structural members by approximately 10% through the utilization of super beams. Furthermore, based on the comparative analysis between the two structures conducted in this study, we have successfully designed a stronger structure with minimal changes in the coefficient of behavior. Additionally, this design has allowed for greater energy dissipation during seismic events, further enhancing the structure's resilience to earthquakes. By comprehensively examining and reinforcing the vulnerability of buildings and infrastructure, along with implementing advanced risk assessment techniques, we can significantly reduce casualties and damages caused by earthquakes in Iran. The findings of this study offer valuable insights for civil engineering professionals in the field of structural engineering, aiding them in designing safer and more resilient structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=modal%20pushover%20analysis" title="modal pushover analysis">modal pushover analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20modification%20factor" title=" response modification factor"> response modification factor</a>, <a href="https://publications.waset.org/abstracts/search?q=high-strength%20concrete" title=" high-strength concrete"> high-strength concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete%20shear%20walls" title=" concrete shear walls"> concrete shear walls</a>, <a href="https://publications.waset.org/abstracts/search?q=high-rise%20building" title=" high-rise building"> high-rise building</a> </p> <a href="https://publications.waset.org/abstracts/167392/estimation-of-the-seismic-response-modification-coefficient-in-the-superframe-structural-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167392.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">155</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">4840</span> The Reenactment of Historic Memory and the Ways to Read past Traces through Contemporary Architecture in European Urban Contexts: The Case Study of the Medieval Walls of Naples</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francesco%20Scarpati">Francesco Scarpati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Because of their long history, ranging from ancient times to the present day, European cities feature many historical layers, whose single identities are represented by traces surviving in the urban design. However, urban transformations, in particular, the ones that have been produced by the property speculation phenomena of the 20th century, often compromised the readability of these traces, resulting in a loss of the historical identities of the single layers. The purpose of this research is, therefore, a reflection on the theme of the reenactment of the historical memory in the stratified European contexts and on how contemporary architecture can help to reveal past signs of the cities. The research work starts from an analysis of a series of emblematic examples that have already provided an original solution to the described problem, going from the architectural detail scale to the urban and landscape scale. The results of these analyses are then applied to the case study of the city of Naples, as an emblematic example of a stratified city, with an ancient Greek origin; a city where it is possible to read most of the traces of its transformations. Particular consideration is given to the trace of the medieval walls of the city, which a long time ago clearly divided the city itself from the outer fields, and that is no longer readable at the current time. Finally, solutions and methods of intervention are proposed to ensure that the trace of the walls, read as a boundary, can be revealed through the contemporary project. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contemporary%20project" title="contemporary project">contemporary project</a>, <a href="https://publications.waset.org/abstracts/search?q=historic%20memory" title=" historic memory"> historic memory</a>, <a href="https://publications.waset.org/abstracts/search?q=historic%20urban%20contexts" title=" historic urban contexts"> historic urban contexts</a>, <a href="https://publications.waset.org/abstracts/search?q=medieval%20walls" title=" medieval walls"> medieval walls</a>, <a href="https://publications.waset.org/abstracts/search?q=naples" title=" naples"> naples</a>, <a href="https://publications.waset.org/abstracts/search?q=stratified%20cities" title=" stratified cities"> stratified cities</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20traces" title=" urban traces"> urban traces</a> </p> <a href="https://publications.waset.org/abstracts/65727/the-reenactment-of-historic-memory-and-the-ways-to-read-past-traces-through-contemporary-architecture-in-european-urban-contexts-the-case-study-of-the-medieval-walls-of-naples" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65727.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">266</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">4839</span> Model Solutions for Performance-Based Seismic Analysis of an Anchored Sheet Pile Quay Wall</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20J.%20W.%20Habets">C.

A more advanced alternative is the Performance-Based Design (PBD) method, which evaluates permanent deformations and amounts of (repairable) damage under seismic loading. The aim of this study is to investigate the suitability of this method for anchored sheet pile quay walls that were not purposely designed for seismic loads. A research methodology is developed in which pseudo-static, permanent-displacement and finite element analysis are employed, calibrated with an experimental reference case that considers a typical anchored sheet pile wall. A reduction factor that accounts for deformation behaviour is determined for pseudo-static analysis. A model to apply traditional permanent displacement analysis on anchored sheet pile walls is proposed. Dynamic analysis is successfully carried out. From the research it is concluded that PBD evaluation can effectively be used for seismic analysis and design of this type of structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anchored%20sheet%20pile%20quay%20wall" title="anchored sheet pile quay wall">anchored sheet pile quay wall</a>, <a href="https://publications.waset.org/abstracts/search?q=simplified%20dynamic%20analysis" title=" simplified dynamic analysis"> simplified dynamic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=performance-based%20design" title=" performance-based design"> performance-based design</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudo-static%20analysis" title=" pseudo-static analysis"> pseudo-static analysis</a> </p> <a href="https://publications.waset.org/abstracts/42173/model-solutions-for-performance-based-seismic-analysis-of-an-anchored-sheet-pile-quay-wall" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42173.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">384</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">4838</span> Behavior of an Elevated Liquid Storage Tank under Near-Fault Earthquakes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Koushik%20Roy">Koushik Roy</a>, <a href="https://publications.waset.org/abstracts/search?q=Sourav%20Gur"> Sourav Gur</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudib%20K.%20Mishra"> Sudib K.

Studies in the recent past explore the effects of pulse type ground motion on the special structures, such as transmission towers in view of their high flexibility. Identically, long period sloshing of liquid in the storage tanks under dynamic loading might increase their failure vulnerability under near-fault pulses. Therefore, the behavior of the elevated liquid storage tank is taken up in this study. Simple lumped mass model is considered, with the bilinear force-deformation hysteresis behavior. Set of near-fault seismic ground acceleration time histories are adopted for this purpose, along with the far-field records for comparison. It has been demonstrated that pulse type motions lead to significant increase of the responses; in particular, sloshing of the fluid mass could be as high as 5 times, then the far field counterpart. For identical storage capacity, slender tanks are found to be more vulnerable than the broad ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=far-field%20motion" title="far-field motion">far-field motion</a>, <a href="https://publications.waset.org/abstracts/search?q=hysteresis" title=" hysteresis"> hysteresis</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20storage%20tank" title=" liquid storage tank"> liquid storage tank</a>, <a href="https://publications.waset.org/abstracts/search?q=near%20fault%20earthquake" title=" near fault earthquake"> near fault earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=sloshing" title=" sloshing"> sloshing</a> </p> <a href="https://publications.waset.org/abstracts/63452/behavior-of-an-elevated-liquid-storage-tank-under-near-fault-earthquakes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63452.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">406</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">4837</span> Preliminary Study of the Cost-Effectiveness of Green Walls: Analyzing Cases from the Perspective of Life Cycle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jyun-Huei%20Huang">Jyun-Huei Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ting-I%20Lee"> Ting-I Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Urban heat island effect is derived from the reduction of vegetative cover by urban development. Because plants can improve air quality and microclimate, green walls have been applied as a sustainable design approach to cool building temperature. By using plants to green vertical surfaces, they decrease room temperature and, as a result, decrease the energy use for air conditioning. Based on their structures, green walls can be divided into two categories, green façades and living walls. A green façade uses the climbing ability of a plant itself, while a living wall assembles planter modules. The latter one is widely adopted in public space, as it is time-effective and less limited. Although a living wall saves energy spent on cooling, it is not necessarily cost-effective from the perspective of a lifecycle analysis. The Italian study shows that the overall benefit of a living wall is only greater than its costs after 47 years of its establishment. In Taiwan, urban greening policies encourage establishment of green walls by referring to their benefits of energy saving while neglecting their low performance on cost-effectiveness. Thus, this research aims at understanding the perception of appliers and consumers on the cost-effectiveness of their living wall products from the lifecycle viewpoint. It adopts semi-structured interviews and field observations on the maintenance of the products. By comparing the two results, it generates insights for sustainable urban greening policies. The preliminary finding shows that stakeholders do not have a holistic sense of lifecycle or cost-effectiveness. Most importantly, a living wall well maintained is often with high input due to the availability of its maintenance budget, and thus less sustainable. In conclusion, without a comprehensive sense of cost-effectiveness throughout a product’s lifecycle, it is very difficult for suppliers and consumers to maintain a living wall system while achieve sustainability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=case%20study" title="case study">case study</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance" title=" maintenance"> maintenance</a>, <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=vertical%20greening" title=" vertical greening"> vertical greening</a> </p> <a href="https://publications.waset.org/abstracts/67160/preliminary-study-of-the-cost-effectiveness-of-green-walls-analyzing-cases-from-the-perspective-of-life-cycle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67160.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">270</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">4836</span> Time-Dependent Behavior of Damaged Reinforced Concrete Shear Walls Strengthened with Composite Plates Having Variable Fibers Spacing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Redha%20Yeghnem">Redha Yeghnem</a>, <a href="https://publications.waset.org/abstracts/search?q=Laid%20Boulefrakh"> Laid Boulefrakh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sid%20Ahmed%20Meftah"> Sid Ahmed Meftah</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelouahed%20Tounsi"> Abdelouahed Tounsi</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Abbas%20Adda%20Bedia"> El Abbas Adda Bedia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the time-dependent behavior of damaged reinforced concrete shear wall structures strengthened with composite plates having variable fibers spacing was investigated to analyze their seismic response. In the analytical formulation, the adherent and the adhesive layers are all modeled as shear walls, using the mixed finite element method (FEM). The anisotropic damage model is adopted to describe the damage extent of the RC shear walls. The phenomenon of creep and shrinkage of concrete has been determined by Eurocode 2. Large earthquakes recorded in Algeria (El-Asnam and Boumerdes) have been tested to demonstrate the accuracy of the proposed method. Numerical results are obtained for non uniform distributions of carbon fibers in epoxy matrices. The effects of damage extent and the delay mechanism creep and shrinkage of concrete are highlighted.

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">294</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">4834</span> Impact of Out-of-Plane Stiffness of the Diaphragm on Deflection of Wood Light-Frame Shear Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20M.%20Bagheri">M.

Where research has lacked is in evaluating the impact of out-of-plane raigidity of the diaphragm on the deflection of shear walls. This study aims at investigating the effect of the diaphragm on the behavior of wood light-frame shear walls, in particular its out-of-plane rigidity was simulated by modeling the floors as beam. The out of plane stiffness of the diaphragm was investigated for idealized (infinitely stiff or flexible) as well as “realistic”. The results showed reductions in the shear wall deflection in the magnitude of approximately 80% considering the out of plane rigidity of the diaphragm. It was also concluded that considering conservative estimates of out-of-plane stiffness might lead to a very significant reduction in deflection and that assuming the floor diaphragm to be infinitely rigid out of plan seems to be reasonable. For diaphragms supported on multiple panels, further reduction in the deflection was observed. More work, particularly at the experimental level, is needed to verify the finding obtained in the numerical investigation related to the effect of out of plane diaphragm stiffness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title="finite element analysis">finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20deflection" title=" lateral deflection"> lateral deflection</a>, <a href="https://publications.waset.org/abstracts/search?q=out-of-plane%20stiffness%20of%20the%20diaphragm" title=" out-of-plane stiffness of the diaphragm"> out-of-plane stiffness of the diaphragm</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20light-frame%20shear%20wall" title=" wood light-frame shear wall"> wood light-frame shear wall</a> </p> <a href="https://publications.waset.org/abstracts/106928/impact-of-out-of-plane-stiffness-of-the-diaphragm-on-deflection-of-wood-light-frame-shear-walls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106928.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">188</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">4833</span> Methods Employed to Mitigate Wind Damage on Ancient Egyptian Architecture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossam%20Mohamed%20Abdelfattah%20Helal%20Hegazi">Hossam Mohamed Abdelfattah Helal Hegazi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Winds and storms are considered crucial weathering factors, representing primary causes of destruction and erosion for all materials on the Earth's surface. This naturally includes historical structures, with the impact of winds and storms intensifying their deterioration, particularly when carrying high-hardness sand particles during their passage across the ground. Ancient Egyptians utilized various methods to prevent wind damage to their ancient architecture throughout the ancient Egyptian periods . One of the techniques employed by ancient Egyptians was the use of clay or compacted earth as a filling material between opposing walls made of stone, bricks, or mud bricks. The walls made of reeds or woven tree branches were covered with clay to prevent the infiltration of winds and rain, enhancing structural integrity, this method was commonly used in hollow layers . Additionally, Egyptian engineers innovated a type of adobe brick with uniformly leveled sides, manufactured from dried clay. They utilized stone barriers, constructed wind traps, and planted trees in rows parallel to the prevailing wind direction. Moreover, they employed receptacles to drain rainwater resulting from wind-loaded rain and used mortar to fill gaps in roofs and structures. Furthermore, proactive measures such as the removal of sand from around historical and archaeological buildings were taken to prevent adverse effects <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=winds" title="winds">winds</a>, <a href="https://publications.waset.org/abstracts/search?q=storms" title=" storms"> storms</a>, <a href="https://publications.waset.org/abstracts/search?q=weathering" title=" weathering"> weathering</a>, <a href="https://publications.waset.org/abstracts/search?q=destruction" title=" destruction"> destruction</a>, <a href="https://publications.waset.org/abstracts/search?q=erosion" title=" erosion"> erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=materials" title=" materials"> materials</a>, <a href="https://publications.waset.org/abstracts/search?q=Earth%27s%20surface" title=" Earth's surface"> Earth's surface</a>, <a href="https://publications.waset.org/abstracts/search?q=historical%20structures" title=" historical structures"> historical structures</a>, <a href="https://publications.waset.org/abstracts/search?q=impact" title=" impact"> impact</a> </p> <a href="https://publications.waset.org/abstracts/184858/methods-employed-to-mitigate-wind-damage-on-ancient-egyptian-architecture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184858.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">71</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">4832</span> Numerical Study of a Nanofluid in a Truncated Cone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20Mahfoud">B.

To be efficient in such tasks, a business process model (BPM) must have high structural quality and high performance. Evidently, evaluating the performance of a business process model is a necessary step to reduce time, cost, while assessing the structural quality aims to improve the understandability and the modifiability of the BPMN model. To achieve these objectives, a set of structural and performance measures have been proposed. Since the diversity of measures, we propose a framework that integrates both structural and performance aspects for classifying them. Our measure classification is based on business process model perspectives (e.g., informational, functional, organizational, behavioral, and temporal), and the elements (activity, event, actor, etc.) involved in computing the measures. Then, we implement this framework in a tool assisting the structural quality and the performance of a business process. The tool helps the designers to select an appropriate subset of measures associated with the corresponding perspective and to calculate and interpret their values in order to improve the structural quality and the performance of the model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=performance" title="performance">performance</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20quality" title=" structural quality"> structural quality</a>, <a href="https://publications.waset.org/abstracts/search?q=perspectives" title=" perspectives"> perspectives</a>, <a href="https://publications.waset.org/abstracts/search?q=tool" title=" tool"> tool</a>, <a href="https://publications.waset.org/abstracts/search?q=classification%20framework" title=" classification framework"> classification framework</a>, <a href="https://publications.waset.org/abstracts/search?q=measures" title=" measures"> measures</a> </p> <a href="https://publications.waset.org/abstracts/120242/a-tool-for-assessing-performance-and-structural-quality-of-business-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120242.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">161</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">4830</span> Experimental Study on Use of Crumb Rubber to Mitigate Expansive Soil Pressures on Basement Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kwestan%20Salimi">Kwestan Salimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jenna%20Jacoby"> Jenna Jacoby</a>, <a href="https://publications.waset.org/abstracts/search?q=Michelle%20Basham"> Michelle Basham</a>, <a href="https://publications.waset.org/abstracts/search?q=Amy%20Cerato"> Amy Cerato</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The extreme annual weather patterns of the central United States have increased the need for underground shelters for protection from destructive tornadic activity. However, very few residential homes have basements due to the added construction expense and the prevalence of expansive soils covering the central portion of the United States. These expansive soils shrink and swell, increasing earth pressure on basement walls. To mitigate the effect of expansive soils on basement walls, this study performed bench-scale tests using a common natural expansive soil mitigated with a backfill layer of crumb rubber. The results revealed that at 80% soil compaction, a 1:6 backfill height to total height ratio produced a 66% reduction in swell pressure. However, this percent reduction decreased to 27% for 90% soil compaction. It was also found that there is a strong linear correlation between compaction percentage and reduction in swell pressure when using the same backfill height to total height ratio. Using this correlation and extrapolating to 95% compaction, the percent reduction in swell pressure was approximately 12%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=expansive%20soils" title="expansive soils">expansive soils</a>, <a href="https://publications.waset.org/abstracts/search?q=swell%2Fshrink" title=" swell/shrink"> swell/shrink</a>, <a href="https://publications.waset.org/abstracts/search?q=swell%20pressure" title=" swell pressure"> swell pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=stabilization" title=" stabilization"> stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=crumb%20rubber" title=" crumb rubber"> crumb rubber</a> </p> <a href="https://publications.waset.org/abstracts/136107/experimental-study-on-use-of-crumb-rubber-to-mitigate-expansive-soil-pressures-on-basement-walls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136107.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">165</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">4829</span> An Atomistic Approach to Define Continuum Mechanical Quantities in One Dimensional Nanostructures at Finite Temperature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Smriti">Smriti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ajeet%20Kumar"> Ajeet Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present a variant of the Irving-Kirkwood procedure to obtain the microscopic expressions of the cross-section averaged continuum fields such as internal force and moment in one-dimensional nanostructures in the non-equilibrium setting. In one-dimensional continuum theories for slender bodies, we deal with quantities such as mass, linear momentum, angular momentum, and strain energy densities, all defined per unit length. These quantities are obtained by integrating the corresponding pointwise (per unit volume) quantities over the cross-section of the slender body. However, no well-defined cross-section exists for these nanostructures at finite temperature. We thus define the cross-section of a nanorod to be an infinite plane which is fixed in space even when time progresses and defines the above continuum quantities by integrating the pointwise microscopic quantities over this infinite plane. The method yields explicit expressions of both the potential and kinetic parts of the above quantities. We further specialize in these expressions for helically repeating one-dimensional nanostructures in order to use them in molecular dynamics study of extension, torsion, and bending of such nanostructures. As, the Irving-Kirkwood procedure does not yield expressions of stiffnesses, we resort to a thermodynamic equilibrium approach to obtain the expressions of axial force, twisting moment, bending moment, and the associated stiffnesses by taking the first and second derivatives of the Helmholtz free energy with respect to conjugate strain measures. The equilibrium approach yields expressions independent of kinetic terms. We then establish the equivalence of the expressions obtained using the two approaches. The derived expressions are used to understand the extension, torsion, and bending of single-walled carbon nanotubes at non-zero temperatures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermoelasticity" title="thermoelasticity">thermoelasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics" title=" molecular dynamics"> molecular dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=one%20dimensional%20nanostructures" title=" one dimensional nanostructures"> one dimensional nanostructures</a>, <a href="https://publications.waset.org/abstracts/search?q=nanotube%20buckling" title=" nanotube buckling"> nanotube buckling</a> </p> <a href="https://publications.waset.org/abstracts/114810/an-atomistic-approach-to-define-continuum-mechanical-quantities-in-one-dimensional-nanostructures-at-finite-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114810.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">132</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">4828</span> Numerical Analysis of Liquid Metal Magnetohydrodynamic Flows in a Manifold with Three Sub-Channels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meimei%20Wen">Meimei Wen</a>, <a href="https://publications.waset.org/abstracts/search?q=Chang%20Nyung%20Kim"> Chang Nyung Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the current study, three-dimensional liquid metal (LM) magneto-hydrodynamic (MHD) flows in a manifold with three sub-channels under a uniform magnetic field are numerically investigated.

High quality select fill is the most suitable backfill material due to its excellent engineering properties and constructability. However, industries are compelled to use low quality, locally available soil because of its ample availability on site. However, several failure cases of such walls are reported, especially subsequent to rainfall events. The stiffness of reinforcement is one of the major factors affecting the performance of RE walls. The present study focused on analyzing the effect of reinforcement stiffness on the performance of complete select fill, complete marginal fill, and hybrid-fill (i.e., combination of select and marginal fills) back-to-back RE walls, immediately after construction and upon rainwater infiltration through finite element modelling. A constant width to height (W/H) ratio of 3 and height (H) of 6 m was considered for the numerical analysis and the stiffness of reinforcement layers was varied from 500 kN/m to 10000 kN/m. Results showed that reinforcement stiffness had a noticeable influence on the response of RE wall, subsequent to construction as well as rainwater infiltration. Facing displacement was found to decrease and maximum reinforcement tension and factor of safety were observed to increase with increasing the stiffness of reinforcement. However, beyond a stiffness of 5000 kN/m, no significant reduction in facing displacement was observed. The behavior of fully marginal fill wall considered in this study was found to be reasonable even after rainwater infiltration when the high stiffness reinforcement layers are used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=back-to-back%20reinforced%20earth%20wall" title="back-to-back reinforced earth wall">back-to-back reinforced earth wall</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20modelling" title=" finite element modelling"> finite element modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=rainwater%20infiltration" title=" rainwater infiltration"> rainwater infiltration</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforcement%20stiffness" title=" reinforcement stiffness "> reinforcement stiffness </a> </p> <a href="https://publications.waset.org/abstracts/129634/influence-of-reinforcement-stiffness-on-the-performance-of-back-to-back-reinforced-earth-wall-upon-rainwater-infiltration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129634.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">158</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">4826</span> Experimental Approach and Numerical Modeling of Thermal Properties of Porous Materials: Application to Construction Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nassima%20Sotehi">Nassima Sotehi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article presents experimental and numerical results concerning the thermal properties of the porous materials used as heat insulator in the buildings sector.

Decisions made at this stage can have an enormous effect on the entire project, as it becomes ever costlier and more difficult to alter the choices made early on in the construction process. Hence, optimisation of the early stages of structural design can provide important efficiencies in terms of cost and time. This paper suggests a structural design optimisation (SDO) framework in which Genetic Algorithms (GAs) may be used to semi-automate the production and optimisation of early structural design alternatives. This framework has the potential to leverage conceptual structural design innovation in Architecture, Engineering and Construction (AEC) projects. Moreover, this framework improves the collaboration between the architectural stage and the structural stage. It will be shown that this SDO framework can make this achievable by generating the structural model based on the extracted data from the architectural model. At the moment, the proposed SDO framework is in the process of validation, involving the distribution of an online questionnaire among structural engineers in the UK. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20information" title="building information">building information</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=BIM" title=" BIM"> BIM</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title="genetic algorithm">genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=GA" title=" GA"> GA</a>, <a href="https://publications.waset.org/abstracts/search?q=architecture-engineering-construction" title=" architecture-engineering-construction"> architecture-engineering-construction</a>, <a href="https://publications.waset.org/abstracts/search?q=AEC" title=" AEC"> AEC</a>, <a href="https://publications.waset.org/abstracts/search?q=optimisation" title=" optimisation"> optimisation</a>, <a href="https://publications.waset.org/abstracts/search?q=structure" title=" structure"> structure</a>, <a href="https://publications.waset.org/abstracts/search?q=design" title=" design"> design</a>, <a href="https://publications.waset.org/abstracts/search?q=population" title=" population"> population</a>, <a href="https://publications.waset.org/abstracts/search?q=generation" title=" generation"> generation</a>, <a href="https://publications.waset.org/abstracts/search?q=selection" title=" selection"> selection</a>, <a href="https://publications.waset.org/abstracts/search?q=mutation" title=" mutation"> mutation</a>, <a href="https://publications.waset.org/abstracts/search?q=crossover" title=" crossover"> crossover</a>, <a href="https://publications.waset.org/abstracts/search?q=offspring" title=" offspring"> offspring</a> </p> <a href="https://publications.waset.org/abstracts/91873/optimisation-of-structural-design-by-integrating-genetic-algorithms-in-the-building-information-modelling-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91873.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">249</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">4824</span> Natural Convection of a Nanofluid in a Conical Container</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brahim%20Mahfoud">Brahim Mahfoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Bendjaghlouli"> Ali Bendjaghlouli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Natural convection is simulated in a truncated cone filled with nanofluid.

However, most MD simulations on tribology have been performed with atomically smooth walls to determine wall slip and friction properties. This study will investigate the effect of porosity, specifically nano-porous walls, on wall slip properties of hydrocarbon oils confined between two walls in a Couette flow. Different pore geometries will be modelled to investigate the effect on wall slip and bulk shear. In this paper, the Polyalphaolefin (PAO) molecules are confined to a stationary and a moving wall. A hybrid force field consisting of different potential energy functions was employed in this MD simulation. Newton’s law defines how those forces will influence the atoms' movements. The interactions among surface atoms were simulated with an Embedded Atom Method (EAM) potential function which can represent the characteristics of metallic arrangements very strongly. We implemented NERD forcefield for intramolecular potential energy function.

Traditional building methodologies, including those using wood, comprise a series of material layers differentiated and separated from each other. This results in the separation of two agencies of building envelope (skin) separate from the structure. However, from a material performance position reliant on additional materials, this is not an efficient strategy for the building. The merits of traditional platform framing are well known. However, its enormous effectiveness within wood-framed construction has seldom led to serious questioning and challenges in defining what it means to build. There are several downsides of using this method, which is less widely discussed. The first and perhaps biggest downside is waste. Second, its reliance on wood assemblies forming walls, floors and roofs conventionally nailed together through simple plate surfaces is structurally inefficient. It requires additional material through plates, blocking, nailers, etc., for stability that only adds to the material waste. In contrast, when we look back at the history of wood construction in airplane and boat manufacturing industries, we will see a significant transformation in the relationship of structure with skin. The history of boat construction transformed from indigenous wood practices of birch bark canoes to copper sheathing over wood to improve performance in the late 18th century and the evolution of merged assemblies that drives the industry today. In 1911, Swiss engineer Emile Ruchonnet designed the first wood monocoque structure for an airplane called the Cigare. The wing and tail assemblies consisted of thin, lightweight, and often fabric skin stretched tightly over a wood frame. This stressed skin has evolved into semi-monocoque construction, in which the skin merges with structural fins that take additional forces. It provides even greater strength with less material. The monocoque, which translates to ‘mono or single shell,’ is a structural system that supports loads and transfers them through an external enclosure system. They have largely existed outside the domain of architecture. However, this uniting of divergent systems has been demonstrated to be lighter, utilizing less material than traditional wood building practices. This paper will examine the role monocoque systems have played in the history of wood construction through lineage of boat and airplane building industries and its design potential for wood building systems in architecture through a case-study examination of a unique wood construction approach. The innovative approach uses a wood monocoque system comprised of interlocking small wood members to create thin shell assemblies for the walls, roof and floor, increasing structural efficiency and wasting less than 2% of the wood. The goal of the analysis is to expand the work of practice and the academy in order to foster deeper, more honest discourse regarding the limitations and impact of traditional wood framing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wood%20building%20systems" title="wood building systems">wood building systems</a>, <a href="https://publications.waset.org/abstracts/search?q=material%20histories" title=" material histories"> material histories</a>, <a href="https://publications.waset.org/abstracts/search?q=monocoque%20systems" title=" monocoque systems"> monocoque systems</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20waste" title=" construction waste"> construction waste</a> </p> <a href="https://publications.waset.org/abstracts/155676/monocoque-systems-the-reuniting-of-divergent-agencies-for-wood-construction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155676.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">82</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">4820</span> Structural Analysis of an Active Morphing Wing for Enhancing UAV Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Kaygan">E.

The concept consists of morphing elements which were designed to provide a rigid and seamless skin while maintaining structural rigidity. The wing structure is first modeled in CATIA V5 then imported into ANSYS for structural analysis. Athena Vortex Lattice method (AVL) is used to estimate aerodynamic response as well as aerodynamic loads of morphing wings, afterwards a structural optimization performed via ANSYS Static. Overall, the results presented in this paper show that the concept provides efficient wing twist while preserving an aerodynamically smooth and compliant surface. Sufficient structural rigidity in bending is also obtained.

This raises questions about how to effectively combine the seismic lateral earth pressure with other loads on buildings, including static lateral earth pressure. When basement walls retain soil with differing exterior grades on opposite sides, the seismic increment of active earth pressure should be considered. Additionally, buildings situated on sloped sites with stepped retention may experience unique dynamic effects due to soil-structure interactions, potentially amplifying the lateral pressures exerted on the retaining walls and influencing the building's response during seismic events. To account for the dynamic effects of the retained soil on the building's responses, it is essential to interconnect the building structure with the surrounding soil to facilitate their interaction as the embedded structure and the surrounding soil move together during an earthquake. Consequently, a finite element model of the building is developed, with the rigid retaining walls and restrained to the floor diaphragms. This paper aims to explore the dynamic effects of retained soil on the lateral stability of buildings and the sensitivity of the building's responses to differences in the retained heights on opposite sides of the building basement. Furthermore, the results are compared with those from a sloped site to evaluate the impact of stepped retention on dynamic soil pressure. These findings will help establish a minimum threshold for differences in retained heights on opposite sides of a building that necessitates the inclusion of dynamic soil pressure in the building's lateral stability analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20earth%20pressures" title="dynamic earth pressures">dynamic earth pressures</a>, <a href="https://publications.waset.org/abstracts/search?q=soil-structure%20interaction" title=" soil-structure interaction"> soil-structure interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=stepped%20retention" title=" stepped retention"> stepped retention</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20retention" title=" building retention"> building retention</a> </p> <a href="https://publications.waset.org/abstracts/196203/evaluating-seismic-earth-pressure-effects-on-building-lateral-stability-sensitivity-to-retention-height-differences-and-sloped-site-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/196203.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">25</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">4817</span> Influence of P-Y Curves on Buckling Capacity of Pile Foundation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Praveen%20Huded">Praveen Huded</a>, <a href="https://publications.waset.org/abstracts/search?q=Suresh%20Dash"> Suresh Dash</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pile foundations are one of the most preferred deep foundation system for high rise or heavily loaded structures. In many instances, the failure of the pile founded structures in liquefiable soils had been observed even in many recent earthquakes. Recent centrifuge and shake table experiments on two layered soil system have credibly shown that failure of pile foundation can occur because of buckling, as the pile behaves as an unsupported slender structural element once the surrounding soil liquefies. However the buckling capacity depends on largely on the depth of soil liquefied and its residual strength. Hence it is essential to check the pile against the possible buckling failure. Beam on non-linear Winkler Foundation is one of the efficient method to model the pile-soil behavior in liquefiable soil. The pile-soil interaction is modelled through p-y springs, different author have proposed different types of p-y curves for the liquefiable soil. In the present paper the influence two such p-y curves on the buckling capacity of pile foundation is studied considering initial geometric and non-linear behavior of pile foundation. The proposed method is validated against experimental results. Significant difference in the buckling capacity is observed for the two p-y curves used in the analysis. A parametric study is conducted to understand the influence of pile diameter, pile flexural rigidity, different initial geometric imperfections, and different soil relative densities on buckling capacity of pile foundation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pile%20foundation" title="Pile foundation ">Pile foundation </a>, <a href="https://publications.waset.org/abstracts/search?q=Liquefaction" title=" Liquefaction"> Liquefaction</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=non-linear%20py%20curve" title=" non-linear py curve"> non-linear py curve</a>, <a href="https://publications.waset.org/abstracts/search?q=Opensees" title=" Opensees"> Opensees</a> </p> <a href="https://publications.waset.org/abstracts/130562/influence-of-p-y-curves-on-buckling-capacity-of-pile-foundation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130562.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">169</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">4816</span> Evaluation of Structural Integrity for Composite Lattice Structure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jae%20Moon%20Im">Jae Moon Im</a>, <a href="https://publications.waset.org/abstracts/search?q=Kwang%20Bok%20Shin"> Kwang Bok Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang%20Woo%20Lee"> Sang Woo Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, evaluation of structural integrity for composite lattice structure was conducted by compressive test.

The determining factor of such development is complex changes in the economic system which may be achieved by making progressive changes in its structure. The structural changes determine the character and the direction of economic development, as well as they include all elements of this system without exception, and their regulated character ensures the most rapid aim achievement. This article has discussed the industrial structure of the agriculture in Russia. With the use of the system of indexes, the article has determined the directions, intensity, and speed of structural shifts. The influence of structural changes on agricultural production development has been found out. It is noticed that the changes in the industrial structure are synchronized with the changes in the organisation and economic structure. Efficiency assessment of structural changes allowed to trace the efficiency of structural changes and elaborate the main directions for agricultural policy improvement. <p
