Seismic Analysis of Multi Storied Building with Shear Walls of Different Shapes

Abstract

A shear wall is a wall that is used to resist the shear, produced due to lateral forces.Shear walls are added to the building interior to provide more strength and stiffness to the building when the exterior walls cannot provide sufficient strength and stiffness.It is necessary to find out the effective shape of shear wall.The present work deals with a study on the improvement shape of shear walls in symmetrical high rise building.In symmetrical buildings, the center of gravity and center of rigidity coincide, so that the shear walls are placed symmetrically.In this work a high rise building with different shapes of shear walls is considered for analysis. The multi storey building with G+14 and G+29 storeys are analyzed for its storey drift and base shear using ETABS software. For the analysis of the building for seismic loading with two different Zones (Zone-III & Zone-V) is considered. The analysis of the building is done by using dynamic method(Response spectrum analysis).
