Abstract
In the seismic resistant design of high-rise structures, shear walls which are constructed along the height of the building are capable of transferring lateral forces from peripheral walls, floors, and roofs to the ground foundation. The main objective of the present study is to determine the effective location for shear walls in a multi-storey building for an optimum seismic response. The “Dynamic Response Spectrum method” of analysis of the building is done using ETABS. The effectiveness of shear walls has been studied by considering four different models. Model-I is a bare frame structural system without a shear wall and the other three models are dual-type structural systems with shear walls at different locations. In this study, a 16x16m plan with G+15 stories RC building with a total height of about 48m is analysed in zone V by providing shear walls of 250mm thick at different locations in the building. From the analysis results it is observed that the model with a shear wall placed at the centre of the building is more effective in resisting seismic forces when compared to other models.
