Seismic Analysis of Symmetrical and Unsymmetrical Multistory Building with Shear Wall and Hybrid Shear Wall

Abstract

Shear walls are structural systems which provide stability to structures from lateral loads like wind, seismic load. Shear walls are added to the building interior to provide more strength and stiffness to the building when the exterior walls cannot provide enough strength and stiffness. It is necessary to provide these shear walls when the tolerable span width ratio for the floor or roof diaphragm is exceeded. Shear walls are mainly flexural members and usually is provided in high- and low-rise buildings to avoid the total collapse of buildings under seismic forces. In this paper 10 storey symmetrical and unsymmetrical building in zone II is consider and analyzed by comparing result obtain by changing various location of shear wall and hybrid shear wall. Analysis is performed to study effect of shear wall location on story drift, displacement and base shear. Analysis is done using ETABs software.
