Effect of Shear Wall Configuration on Seismic Performance of Building

Abstract—One of the most commonly used lateral load resisting systems in buildings is shear wall system. It is well-established fact that shear walls are quite effective in seismic load resistance of medium-rise to high-rise reinforced concrete buildings. Shear walls have very high in-plane stiffness and strength, which can be used simultaneously to resist large horizontal loads and support gravity loads, making them quite beneficial in seismic performance of buildings. Lot of literature is available to design and analysis of shear wall; the effect of different parameters such as: time period, wall density, slenderness ratio, on seismic behavior of shear wall buildings has been studied as well. However, the decision about the location of shear wall in multistory building and its effect on performance against earthquakes is not much discussed in the literatures. In the present study main focus is to determine the effect of shear wall configuration on seismic performance of buildings. Time history analysis has been done to buildings with different number of stories and various configurations with same plan. The top story displacements have been obtained and compared to each other for all models to meet the effect of shear wall configuration on seismic performance of buildings. The analysis and design of models have been studied based on IS codes, and SAP 2000 software have been used for this purpose.
