development whenever it offers a better alternative, or is complementary, to current solutions. Green walls and living facades often provide healthy alternatives to traditional grey infrastructures, offering many benefits for both citizens and cities. Beyond the ability to improve environmental conditions and quality of life, they can augment the energy efficiency of buildings, enhance biodiversity and deliver a range of ecosystem services such as water purification, reduction of the urban heat island effect, improvement of air quality and climate change adaptation. For this communication, a systematic survey of the existing green walls and living facades in Portugal was carried out. Different systems were analyzed and compared in terms of dimensions, constructive solutions, vegetative species, maintenance necessities and environmental aspects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20buildings" title="green buildings">green buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20walls" title=" green walls"> green walls</a>, <a href="https://publications.waset.org/abstracts/search?q=living%20facades" title=" living facades"> living facades</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability%20construction" title=" sustainability construction"> sustainability construction</a> </p> <a href="https://publications.waset.org/abstracts/63673/green-walls-and-living-facades-the-portuguese-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63673.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">425</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">3023</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">265</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">3022</span> Agriroofs and Agriwalls: Applications of Food Production in Green Roofs and Green Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20M.%20Elmazek">Eman M.

The idea takes great steps towards the future of sustainable design due to its many benefits. However, there are many barriers and constraints. Economical, structural, and knowledge barriers prevent the spread of the usage of green roofs and living walls. Understanding the benefits and expanding them will spread the idea. Benefits provided by these green spots interrupt and maintain the current urban cover. Food production is one of the benefits of green roofs. It can save money and energy spent in food transportation. The goal of this paper is to put a better understanding of implementing green systems. The paper aims to identify gains versus challenges facing the technology. It surveys with case studies buildings with green roofs and walls used for food production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20roof" title="green roof">green roof</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20walls" title=" green walls"> green walls</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20farming" title=" urban farming"> urban farming</a>, <a href="https://publications.waset.org/abstracts/search?q=roof%20herb%20garden" title=" roof herb garden"> roof herb garden</a> </p> <a href="https://publications.waset.org/abstracts/46610/agriroofs-and-agriwalls-applications-of-food-production-in-green-roofs-and-green-walls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46610.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">530</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">3021</span> Semi Empirical Equations for Peak Shear Strength of Rectangular Reinforced Concrete Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Kezmane">Ali Kezmane</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Boukais"> Said Boukais</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohand%20Hamizi"> Mohand Hamizi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an analytical study on the behavior of reinforced concrete walls with rectangular cross section.

These walls may take many forms due to their functions and locations in the building. In Palestine, the most lateral resisting forces construction forms is the cantilever shear walls system. It is thus of prime importance to study the rigidity of these walls. The virtual work theorem is used to derive the total lateral deflection of cantilever shear walls due to flexural and shear deformation. The case of neglecting the shear deformation in the walls is also studied, and it is found that the wall height to length aspect ratio (H/B) plays a major role in calculating the lateral deflection and the rigidity of such walls. When the H/B is more than or equal to 3.7, the shear deformation may be neglected from the calculation of the lateral deflection. Moreover, the walls with the same material properties, same lateral load value, and same aspect ratio, shall have the same of both the lateral deflection and the rigidity. Finally, an equation to calculate the total rigidity and total deflection of such walls is derived by using the virtual work theorem for a cantilever beam. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cantilever%20shear%20walls" title="cantilever shear walls">cantilever shear walls</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural%20deformation" title=" flexural deformation"> flexural deformation</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=lateral%20loads" title=" lateral loads"> lateral loads</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20shear%20walls" title=" reinforced concrete shear walls"> reinforced concrete shear walls</a>, <a href="https://publications.waset.org/abstracts/search?q=rigidity" title=" rigidity"> rigidity</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20deformation" title=" shear deformation"> shear deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20work%20theorem" title=" virtual work theorem"> virtual work theorem</a> </p> <a href="https://publications.waset.org/abstracts/99514/simplified-equations-for-rigidity-and-lateral-deflection-for-reinforced-concrete-cantilever-shear-walls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99514.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">219</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">3019</span> Evaluation of Flange Effects on the Lateral In-Plane Response of Brick Masonry Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hizb%20Ullah%20Sajid">Hizb Ullah Sajid</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ashraf"> Muhammad Ashraf</a>, <a href="https://publications.waset.org/abstracts/search?q=Naveed%20Ahmad%20Qaisar%20Ali"> Naveed Ahmad Qaisar Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Sikandar%20Hayat%20Sajid"> Sikandar Hayat Sajid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research study investigates experimentally the effects of flanges (transverse walls) on the lateral in-plane response of brick masonry walls.

In particular the damage mechanism, lateral in-plane stiffness & strength, deformability and energy dissipation of the two classes of walls are compared and the differences are quantified to help understand the effects of flanges on the in-plane response of masonry walls. The available analytical models for the in-plane shear strength & deformation evaluation of masonry walls are critically analyzed.

In a hot climate area, there is a need for a new sustainable alternative that is more convenient for an existing situation. The Building envelope controls the heat transfer between the outside and inside the building. While the building façade is the most critical part, types of façade material play a vital role in influences of the energy demand for heating and cooling due to exposure to direct solar radiation throughout the day. Since the beginning of the twentieth century, the use of curtain walls in office buildings façades started to increase rapidly, which lead to more cooling loads in energy consumption. Integrating the living wall system in urban areas as a sustainable renovation and energy-saving method for the built environment will reduce the energy demand of buildings and will also provide environmental benefits. Also, it will balance the urban ecology and enhance urban life quality. The results show that the living wall systems reduce the internal temperature up to 4.0 °C. This research carries on an analytical study by highlighting the different types of living wall systems and verifying their thermal performance, energy-saving, and life potential on the building. These assessing criteria include the reason for using the Living wall systems in the building façade as well as the effect it has upon the surrounding environment. Finally, the paper ends with concluding the effect of using living wall systems on building. And, it suggests a system as long-lasting, and energy-efficient solution to be applied in curtain wall façades in a hot climate area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=living%20wall%20systems" title="living wall systems">living wall systems</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=curtain%20walls" title=" curtain walls"> curtain walls</a>, <a href="https://publications.waset.org/abstracts/search?q=energy-saving" title=" energy-saving"> energy-saving</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20life%20quality" title=" urban life quality "> urban life quality </a> </p> <a href="https://publications.waset.org/abstracts/113776/living-wall-systems-an-approach-for-reducing-energy-consumption-in-curtain-wall-facades" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113776.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">141</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">3016</span> Analysis of Experimentally Designed Soundproof Gypsum Partition Wall's Sections in Terms of Structural Engineering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulkerim%20Ilgun">Abdulkerim Ilgun</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Javid%20Zia"> Ahmad Javid Zia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In developing countries, the urban populations are increasing rapidly and with this increment the residential areas are experiencing major problems. Construction of high-rise buildings in confined spaces is one of the most practical solutions for this problem. However, by living in high-rise buildings and sharing common residential areas, residents will face many problems. Irritating sound problem which is known as noise is one of the major problems mentioned above. The second most important problem is the weight of the high-rise buildings which makes the structure more vulnerable to earthquakes. To decrease earthquake loads it’s very important to decrease the weight of the buildings. To solve the problem of noise and keep the building weight at minimum level, experimentally designed soundproof gypsum partition wall which has optimum thickness has been used in high-rise story building and the results have been compared with ordinary brick partition walls. In this compression the effect of weights of soundproof gypsum walls and ordinary brick walls in accordance to structural engineering have been investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cellubor" title="cellubor">cellubor</a>, <a href="https://publications.waset.org/abstracts/search?q=gypsum%20board" title=" gypsum board"> gypsum board</a>, <a href="https://publications.waset.org/abstracts/search?q=gypsum%20partition%20walls" title=" gypsum partition walls"> gypsum partition walls</a>, <a href="https://publications.waset.org/abstracts/search?q=light%20partition%20walls" title=" light partition walls"> light partition walls</a>, <a href="https://publications.waset.org/abstracts/search?q=noise" title=" noise"> noise</a>, <a href="https://publications.waset.org/abstracts/search?q=sound" title=" sound"> sound</a> </p> <a href="https://publications.waset.org/abstracts/38732/analysis-of-experimentally-designed-soundproof-gypsum-partition-walls-sections-in-terms-of-structural-engineering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38732.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">307</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">3015</span> A Comparison between Modelled and Actual Thermal Performance of Load Bearing Rammed Earth Walls in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Hafez">H.

The objective of this paper is to outline how the thermal performance of rammed earth walls compares to conventional reinforced concrete skeleton and red brick in-fill walls. For this sake, the indoor temperature and relative humidity of a classroom built with rammed earth walls and a vaulted red brick roof in the area of Behbeit, Giza, Egypt were measured hourly over 6 months using smart sensors. These parameters for the rammed earth walls were later also compared against the values obtained using a 'DesignBuilder v5' model to verify the model assumptions. The thermal insulation of rammed earth walls was found to be 30% better than this of the redbrick infill, and the recorded data were found to be almost 90% similar to the modelled values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rammed%20earth" title="rammed earth">rammed earth</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20insulation" title=" thermal insulation"> thermal insulation</a>, <a href="https://publications.waset.org/abstracts/search?q=indoor%20air%20quality" title=" indoor air quality"> indoor air quality</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20builder" title=" design builder"> design builder</a> </p> <a href="https://publications.waset.org/abstracts/99687/a-comparison-between-modelled-and-actual-thermal-performance-of-load-bearing-rammed-earth-walls-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99687.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">146</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">3014</span> Effect of Boundary Retaining Walls Properties on the Raft Foundations Behaviour</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hussein">Mohamed Hussein</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper studies the effect of boundary retaining walls properties on the behavior of the raft foundation.

The two dual systems are designed to resist the total design lateral force in proportion to their lateral stiffness. The response of the combination of braces and shear walls has not yet been studied therefore has practically no work to refer to. The combination may prove to be more effective in lateral load resistance by employing the peculiar advantages of shear walls and braces simultaneously and may also improve the architectural appearance of structures.

RC walls are subjected to axial forces in common and the effect of axial forces on the strength loss of the fire damaged walls has not been investigated. This paper aims at investigating temperature distribution on fire damaged concrete walls having different axial loads. In the experiments, a variable of specimens is axial force ratio. RC walls are fabricated with 150mm of wall thicknesses, 750mm of lengths and 1,300mm of heights having concrete strength of 24MPa. After curing, specimens are heated on one surface with ISO-834 standard time-temperature curve for 2 hours and temperature distributions during the test are measured using thermocouples inside the walls. The experimental results show that the temperature of the RC walls exposed to fire increases as axial force ratio increases. To verify the experiments, finite element (FE) models are generated for coupled temperature-structure analyses. The analytical results of thermal behaviors are in good agreement with the experimental results. The predicted displacement of the walls decreases when the axial force increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axial%20force%20ratio" title="axial force ratio">axial force ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=fire" title=" fire"> fire</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20wall" title=" reinforced concrete wall"> reinforced concrete wall</a>, <a href="https://publications.waset.org/abstracts/search?q=residual%20strength" title=" residual strength"> residual strength</a> </p> <a href="https://publications.waset.org/abstracts/36359/investigation-of-fire-damaged-reinforced-concrete-walls-with-axial-force" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36359.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">461</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">3011</span> Modular, Responsive, and Interactive Green Walls - A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Flaviu%20Mihai%20Frigura-Lliasa">Flaviu Mihai Frigura-Lliasa</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreea%20Anamaria%20Anghel"> Andreea Anamaria Anghel</a>, <a href="https://publications.waset.org/abstracts/search?q=Attila%20Simo"> Attila Simo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the beauty, usefulness, science, constantly changing, constantly evolving features, and most of the time, mystery it involves, nature-based art is seen as a both modern and timeless direction that has been extensively used in design. The goal of the team's activities was to experiment with ways of fusing the two most common contemporary ways of referring to green installations, that is, either in a pure artistic or in an ecological manner, and creating a living, dynamic, interactive installation capable of both receiving and interpreting external factors, such as natural and human stimuli, that would not only determine some of the mechanism's presets. By consequent, a complex experiment made up of various research and project stages was elaborated in order to transform an idea into an actual interactive green installation within months thanks to the interaction, teamwork, and design processes undertaken throughout the academic years by both university lecturers and some of our students. The outcomes would lead to the development of a dynamic artwork called "Modgrew" as well as the introduction of experiment-based learning at the Timisoara Faculty of Architecture and Urban Planning, as well as at the Faculty of Electrical and Power Engineering, for the green wall automation issues. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20design" title="green design">green design</a>, <a href="https://publications.waset.org/abstracts/search?q=living%20walls" title=" living walls"> living walls</a>, <a href="https://publications.waset.org/abstracts/search?q=modular%20structure" title=" modular structure"> modular structure</a>, <a href="https://publications.waset.org/abstracts/search?q=interactive%20proof%20of%20concept" title=" interactive proof of concept"> interactive proof of concept</a> </p> <a href="https://publications.waset.org/abstracts/166969/modular-responsive-and-interactive-green-walls-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166969.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">76</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">3010</span> Moment-Curvature Relation for Nonlinear Analysis of Slender Structural Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Dehghan">E.

Since behavior of bending members can be explained by moment–curvature relation, therefore, an analytical model is proposed based on moment–curvature relation for slender structural walls. The moment–curvature relationships of RC sections are constructed through section analysis. Governing equations describing the bond-slip behavior in walls are derived and applied to moment–curvature relations. For the purpose of removing the imprecision in analytical results, the plastic hinge length is included in the finite element modeling. Finally, correlation studies between analytical and experimental results are conducted with the objective to establish the validity of the proposed algorithms. The results show that bond-slip effect is more significant in walls subjected to larger axial compression load. Moreover, preferable results are obtained when ultimate strain of concrete is assumed conservatively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20analysis" title="nonlinear analysis">nonlinear analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=slender%20structural%20walls" title=" slender structural walls"> slender structural walls</a>, <a href="https://publications.waset.org/abstracts/search?q=moment-curvature%20relation" title=" moment-curvature relation"> moment-curvature relation</a>, <a href="https://publications.waset.org/abstracts/search?q=bond-slip" title=" bond-slip"> bond-slip</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20hinge%20length" title=" plastic hinge length"> plastic hinge length</a> </p> <a href="https://publications.waset.org/abstracts/43118/moment-curvature-relation-for-nonlinear-analysis-of-slender-structural-walls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43118.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">317</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">3009</span> Seismic Response of Large-Scale Rectangular Steel-Plate Concrete Composite Shear Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siamak%20Epackachi">Siamak Epackachi</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20S.%20Whittaker"> Andrew S.

Twin steel plates-composite shear walls contain very high ultimate bearing capacity and ductility, which have great potential to be applied in the super high-rise buildings and special structures. In this paper, we analyzed the basic characteristics and stress mechanism of the twin steel plates-composite shear walls. Specifically, we analyzed the effects of the steel plate thickness, wall thickness and concrete strength on the bearing capacity of the twin steel plates-composite shear walls. The analysis results indicate that：（1）the initial shear stiffness and ultimate shear-carrying capacity is not significantly affected by the thickness of concrete wall but by the class of concrete,（2）both factors significantly impact the shear distribution of the shear walls in ultimate shear-carrying capacity. The technique of twin steel plates-composite shear walls has been successfully applied in the construction of a 88-meter Huge Statue of Buddha located in Hunan Province, China.

However, in reality, a shear flow would develop in non-rectangular sections, where the longitudinal strains in between the web and flanges of the element would lag behind those at the boundary ends. This phenomenon, known as shear lag, can significantly reduce the expected moment capacity of non-rectangular reinforced concrete walls. This study focuses on shear lag effects in reinforced concrete U-shaped walls, which are commonly used as lateral load resisting elements in reinforced concrete buildings. An extensive number of finite element modelling analyses are conducted to estimate the vertical strain distributions across the web and flanges of a U-shaped wall with different axial load ratios and longitudinal reinforcement detailing. The results show that shear lag effects are prominent and sometimes significant in U-shaped walls, particularly for the wall sections perpendicular to the direction of loading. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shear%20lag" title="shear lag">shear lag</a>, <a href="https://publications.waset.org/abstracts/search?q=walls" title=" walls"> walls</a>, <a href="https://publications.waset.org/abstracts/search?q=U-shaped" title=" U-shaped"> U-shaped</a>, <a href="https://publications.waset.org/abstracts/search?q=moment-curvature" title=" moment-curvature"> moment-curvature</a> </p> <a href="https://publications.waset.org/abstracts/92183/effective-width-of-reinforced-concrete-u-shaped-walls-due-to-shear-lag-effects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92183.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">211</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">3005</span> Automating 2D CAD to 3D Model Generation Process: Wall pop-ups</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohit%20Gupta">Mohit Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Chialing%20Wei"> Chialing Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Czerniawski"> Thomas Czerniawski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we have built a neural network that can detect walls on 2D sheets and subsequently create a 3D model in Revit using Dynamo. The training set includes 3500 labeled images, and the detection algorithm used is YOLO. Typically, engineers/designers make concentrated efforts to convert 2D cad drawings to 3D models. This costs a considerable amount of time and human effort. This paper makes a contribution in automating the task of 3D walls modeling. 1. Detecting Walls in 2D cad and generating 3D pop-ups in Revit. 2. Saving designer his/her modeling time in drafting elements like walls from 2D cad to 3D representation. An object detection algorithm YOLO is used for wall detection and localization. The neural network is trained over 3500 labeled images of size 256x256x3. Then, Dynamo is interfaced with the output of the neural network to pop-up 3D walls in Revit. The research uses modern technological tools like deep learning and artificial intelligence to automate the process of generating 3D walls without needing humans to manually model them. Thus, contributes to saving time, human effort, and money. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neural%20networks" title="neural networks">neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=Yolo" title=" Yolo"> Yolo</a>, <a href="https://publications.waset.org/abstracts/search?q=2D%20to%203D%20transformation" title="2D to 3D transformation">2D to 3D transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=CAD%20object%20detection" title=" CAD object detection"> CAD object detection</a> </p> <a href="https://publications.waset.org/abstracts/144132/automating-2d-cad-to-3d-model-generation-process-wall-pop-ups" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144132.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">144</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">3004</span> Utilizing Fiber-Based Modeling to Explore the Presence of a Soft Storey in Masonry-Infilled Reinforced Concrete Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akram%20Khelaifia">Akram Khelaifia</a>, <a href="https://publications.waset.org/abstracts/search?q=Salah%20Guettala"> Salah Guettala</a>, <a href="https://publications.waset.org/abstracts/search?q=Nesreddine%20Djafar%20Henni"> Nesreddine Djafar Henni</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Chebili"> Rachid Chebili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent seismic events have underscored the significant influence of masonry infill walls on the resilience of structures. The irregular positioning of these walls exacerbates their adverse effects, resulting in substantial material and human losses. Research and post-earthquake evaluations emphasize the necessity of considering infill walls in both the design and assessment phases. This study delves into the presence of soft stories in reinforced concrete structures with infill walls. Employing an approximate method relying on pushover analysis results, fiber-section-based macro-modeling is utilized to simulate the behavior of infill walls. The findings shed light on the presence of soft first stories, revealing a notable 240% enhancement in resistance for weak column—strong beam-designed frames due to infill walls. Conversely, the effect is more moderate at 38% for strong column—weak beam-designed frames. Interestingly, the uniform distribution of infill walls throughout the structure's height does not influence soft-story emergence in the same seismic zone, irrespective of column-beam strength. In regions with low seismic intensity, infill walls dissipate energy, resulting in consistent seismic behavior regardless of column configuration. Despite column strength, structures with open-ground stories remain vulnerable to soft first-story emergence, underscoring the crucial role of infill walls in reinforced concrete structural design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=masonry%20infill%20walls" title="masonry infill walls">masonry infill walls</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20Storey" title=" soft Storey"> soft Storey</a>, <a href="https://publications.waset.org/abstracts/search?q=pushover%20analysis" title=" pushover analysis"> pushover analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber%20section" title=" fiber section"> fiber section</a>, <a href="https://publications.waset.org/abstracts/search?q=macro-modeling" title=" macro-modeling"> macro-modeling</a> </p> <a href="https://publications.waset.org/abstracts/182588/utilizing-fiber-based-modeling-to-explore-the-presence-of-a-soft-storey-in-masonry-infilled-reinforced-concrete-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182588.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">67</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">3003</span> Design and Optimization of Soil Nailing Construction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fereshteh%20Akbari">Fereshteh Akbari</a>, <a href="https://publications.waset.org/abstracts/search?q=Farrokh%20Jalali%20Mosalam"> Farrokh Jalali Mosalam</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Hedayatifar"> Ali Hedayatifar</a>, <a href="https://publications.waset.org/abstracts/search?q=Amirreza%20Aminjavaheri"> Amirreza Aminjavaheri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The soil nailing is an effective method to stabilize slopes and retaining structures.

The behavior of coupled shear walls is mainly governed by the coupling beams. The coupling beams are designed for ductile inelastic behavior in order to dissipate energy. The base of the shear walls may be designed for elastic or ductile inelastic behavior. The amount of energy dissipation depends on the yield moment capacity and plastic rotation capacity of the coupling beams. In this paper, an analytical model of coupling beam was developed to calculate the rotations and moment capacities of coupling beam with conventional reinforcement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20studies" title="design studies">design studies</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20model%28s%29" title=" computational model(s)"> computational model(s)</a>, <a href="https://publications.waset.org/abstracts/search?q=case%20study%2Fstudies" title=" case study/studies"> case study/studies</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=coupling%20beam" title=" coupling beam"> coupling beam</a> </p> <a href="https://publications.waset.org/abstracts/3310/investigation-on-the-behavior-of-conventional-reinforced-coupling-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3310.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">476</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">3001</span> The Effects of Placement and Cross-Section Shape of Shear Walls in Multi-Story RC Buildings with Plan Irregularity on Their Seismic Behavior by Using Nonlinear Time History Analyses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Aminnia">Mohammad Aminnia</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmood%20Hosseini"> Mahmood Hosseini </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Environmental and functional conditions sometimes necessitate the architectural plan of the building to be asymmetric, and this result in an asymmetric structure. In such cases, finding an optimal pattern for locating the components of the lateral load bearing system, including shear walls, in the building’s plan is desired. In case of shear walls, in addition to the location, the shape of the wall cross-section is also an effective factor. Various types of shear wall and their proper layout might come effective in better stiffness distribution and more appropriate seismic response of the building. Several studies have been conducted in the context of analysis and design of shear walls; however, few studies have been performed on making decisions for the location and form of shear walls in multi-story buildings, especially those with irregular plan. In this study, an attempt has been made to obtain the most reliable seismic behavior of multi-story reinforced concrete vertically chamfered buildings by using more appropriate shear walls form and arrangement in 7-, 10-, 12-, and 15-story buildings. The considered forms and arrangements include common rectangular walls and L-, T-, U- and Z-shaped plan, located as the core or in the outer frames of the building structure. Comparison of seismic behaviors of the buildings, including maximum roof displacement, and particularly the formation of plastic hinges and their distribution in the buildings’ structures, have been done based on the results of a series of nonlinear time history analyses by using a set of selected earthquake records. Results show that shear walls with U-shaped cross-section, placed as the building central core, and also walls with Z-shaped cross-section, placed at the corners give the building more reliable seismic behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vertically%20chamfered%20buildings" title="vertically chamfered buildings">vertically chamfered buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20time%20history%20analyses" title=" non-linear time history analyses"> non-linear time history analyses</a>, <a href="https://publications.waset.org/abstracts/search?q=l-" title=" l-"> l-</a>, <a href="https://publications.waset.org/abstracts/search?q=t-" title=" t-"> t-</a>, <a href="https://publications.waset.org/abstracts/search?q=u-%20and%20z-shaped%20plan%20walls" title=" u- and z-shaped plan walls"> u- and z-shaped plan walls</a> </p> <a href="https://publications.waset.org/abstracts/37110/the-effects-of-placement-and-cross-section-shape-of-shear-walls-in-multi-story-rc-buildings-with-plan-irregularity-on-their-seismic-behavior-by-using-nonlinear-time-history-analyses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37110.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">258</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">3000</span> Thermodynamic Performance Tests for 3D Printed Steel Slag Powder Concrete Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Li%20Guoyou">Li Guoyou</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Tao"> Zhang Tao</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji%20Wenzhan"> Ji Wenzhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Huo%20Liang"> Huo Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Lin%20Xiqiang"> Lin Xiqiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Nan"> Zhang Nan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The three dimensional (3D) printing technology has undergone rapid development in the last few years and it is possible to print engineering structures. 3D printing buildings use wastes from constructions, industries and mine tailings as “ink”, and mix it with property improved materials, such as cement, fiber etc. This paper presents a study of the Thermodynamic performance of 3D printed walls using cement and steel slag powder. Analyses the thermal simulation regarding 3D printed walls and solid brick wall by the way of the hot-box methods and the infrared technology, and the results were contrasted with theoretical calculation. The results show that the excellent thermodynamic performance of 3D printed concrete wall made it suitable as the partial materials for self-thermal insulation walls in residential buildings. The thermodynamic performance of 3D printed concrete walls depended on the density of materials, distribution of holes, and the filling materials. Decreasing the density of materials, increasing the number of holes or replacing the filling materials with foamed concrete could improve its thermodynamic performance significantly. The average of heat transfer coefficient and thermal inertia index of 3D printed steel slag powder concrete wall all better than the traditional solid brick wall with a thickness of 240mm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete" title="concrete">concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20printed%20walls" title=" 3D printed walls"> 3D printed walls</a>, <a href="https://publications.waset.org/abstracts/search?q=thermodynamic%20performance" title=" thermodynamic performance"> thermodynamic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20slag%20powder" title=" steel slag powder"> steel slag powder</a> </p> <a href="https://publications.waset.org/abstracts/92165/thermodynamic-performance-tests-for-3d-printed-steel-slag-powder-concrete-walls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92165.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">183</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">2999</span> Finite Element Analysis of Reinforced Structural Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mintesinot%20Teshome%20Mengsha">Mintesinot Teshome Mengsha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reinforced concrete structural walls are provided in structures to decrease horizontal displacements under seismic loads. The cyclic lateral load resistance capacity of a structural wall is controlled by two parameters, the strength and the ductility; it is better to have the shear strength somewhat greater than the compression to prevent shear failure, which is brittle, sudden and of serious consequence. Due to architectural and functional reasons, small openings are provided in this important structural part. The main objective of this study is to investigate the finite element of RC structural walls with small openings subjected to cyclic load using the finite element approach.

They are also an economical way to meet everyday earth retention needs for highway and bridge grade separations, railroads, commercial and residential developments. But, existing design guidelines (FHWA/BS/ IS codes) do not provide a mechanistic approach for the design of back-to-back reinforced retaining walls. The settlement analysis of such structures is limited in the literature. A better understanding of the deformations of this wall system requires an analytical tool that incorporates the properties of backfill material, foundation soil, and geosynthetic reinforcement, and account for the soil–structure interactions in a realistic manner. This study was conducted to investigate the effect of reinforced back-to-back MSE walls on wall settlements and facing deformations. Back-to-back reinforced retaining walls were modeled and compared using commercially available finite difference package FLAC 2D. Parametric studies were carried out for various angles of shearing resistance of backfill material and foundation soil, and the axial stiffness of the reinforcement. A 6m-high wall was modeled, and the facing panels were taken as full-length panels with nominal thickness. Reinforcement was modeled as cable elements (two-dimensional structural elements). Interfaces were considered between soil and wall, and soil and reinforcement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=back-to-back%20walls" title="back-to-back walls">back-to-back walls</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20modeling" title=" numerical modeling"> numerical modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20wall" title=" reinforced wall"> reinforced wall</a>, <a href="https://publications.waset.org/abstracts/search?q=settlement" title=" settlement"> settlement</a> </p> <a href="https://publications.waset.org/abstracts/66038/settlement-analysis-of-back-to-back-mechanically-stabilized-earth-walls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66038.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">303</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">2997</span> Effects of Directivity and Fling Step on Buildings Equipped with J-Hook Sandwich Composite Walls and Reinforced Concrete Shear Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Majid%20Saaly">Majid Saaly</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahriar%20Tavousi%20Tafreshi"> Shahriar Tavousi Tafreshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Nazari%20Afshar"> Mehdi Nazari Afshar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The structural systems with the sandwich composite wall (SCSSC) are of very popular due to their ductileness and competency to swallow more energy and power than standard reinforced concrete shear walls.

SCSSCs showed acceptable seismic performance under experimental tests and cyclic loading from the points of view of in-plane and out-of-plane shear and flexural interaction, in-plane punching shear, and compressive behavior. The use of sandwich composite walls with J-hook connectors has a significant effect on energy dissipation and reduction of dynamic responses of mid-rise and high-rise structural models.

Considering the criteria of experts' opinions (cost and reuse), the amount of embodied energy of the materials, as well as the amount of waste of electricity and gas of different materials of the walls, with the help of the AHP weighting technique and finally with the TOPSIS technique, the best type of materials in the order of 1- 3-D Panel 2-ICF-, 3-Cement block with pumice, 4-Wallcrete block, 5-Clay block, 6-Autoclaved Aerated Concrete (AAC), 7-Foam cement block, 8-Aquapanel and 9-Reinforced concrete wall for use in The walls of the buildings were proposed in Sari city. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimum%20materials" title="optimum materials">optimum materials</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20walls" title=" building walls"> building walls</a>, <a href="https://publications.waset.org/abstracts/search?q=moderate%20and%20humid%20climate" title=" moderate and humid climate"> moderate and humid climate</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20architecture" title=" sustainable architecture"> sustainable architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=AHP-TOPSIS%20technique" title=" AHP-TOPSIS technique"> AHP-TOPSIS technique</a> </p> <a href="https://publications.waset.org/abstracts/165462/ranking-of-optimal-materials-for-building-walls-from-the-perspective-of-cost-and-waste-of-electricity-and-gas-energy-using-ahp-topsis-1-technique-study-example-sari-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165462.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">77</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">2995</span> The Effects of Spatial Dimensions and Relocation and Dimensions of Sound Absorbers in a Space on the Objective Parameters of Sound</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Kavraz">Mustafa Kavraz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigated the differences in the objective parameters of sound depending on the changes in the lengths of the lateral surfaces of a space and on the replacement of the sound absorbers that are placed on these surfaces. To this end, three models of room were chosen. The widths and heights of these rooms were the same but the lengths of the rooms were changed. The smallest room was 8 m. wide and 10 m. long. The lengths of the other two rooms were 15 m. and 20 m. For each model, the differences in the objective parameters of sound were determined by keeping all the material in the space intact and by changing only the positions of the sound absorbers that were placed on the walls. The sound absorbers that were used on the walls were of two different sizes. The sound absorbers that were placed on the walls were 4 m and 8 m. long and story-height (3 m.). In all model room types, the sound absorbers were placed on the long walls in three different ways: at the end of the long walls where the long walls meet the front wall; at the end of the long walls where the long walls meet the back wall; and in the middle part of the long walls. Except for the specially placed sound absorbers, the ground, wall and ceiling surfaces were covered with three different materials. There were no constructional elements such as doors and windows on the walls. On the surfaces, the materials specified in the Odeon 10 material library were used as coating material. Linoleum was used as flooring material, painted plaster as wall coating material and gypsum boards as ceiling covering (2 layers with a total of 32 mm. thickness). These were preferred due to the fact that they are the commonly used materials for these purposes.
