Effect of Location in Plan of Reinforced Concrete Shear Walls on Nonlinear Behavior

Abstract

In recent years, there has been a significant increase in the number of residential and commercial buildings. This significant increase requires much attention to the effects of earthquake loads on structural systems and the resistance of structures against seismic forces. Structural systems are subjected to large lateral displacement due to seismic effects. Reinforced concrete shear wall buildings that are a popular choice in many earthquakes prone countries resist large earthquake loads and support gravity loads and also prevent large lateral displacements. Reinforced concrete shear walls are widely used in these structural systems to provide appropriate strength and stiffness to resist lateral displacements caused by earthquake loads. Shear wall generally gives better response to earthquake loads when it is provided at an effective location of the building plan. Therefore, positioning of shear wall has evident influence on the overall behavior of the building. Main objective of this study is to examine the actual behavior of shear wall for different locations. For this purpose, nonlinear static analysis has been performed for three different positioning of RC shear wall designed according to Turkish Seismic Code (TSC-2018). The sample buildings have 8-storey with columns, beams, slabs, and RC shear walls. The RC shear walls have same length and width for three different cases, so the results are affected by the arrangement and positioning of RC shear walls only.
