Shear wall is a structural element used to resist lateral loads in the high rise buildings. Shear walls act as major earth quake resisting members and simultaneously resist the gravity loads Shear walls are specially designed structural walls include in the buildings to resist horizontal forces that are induces in the plane wall due to wind, earth quake and other forces. They are mainly flexural members and usually provided in high rise buildings to avoid the total collapse of the high rise buildings to avoid the total collapse of the high rise buildings under seismic forces. In this study a 20 storey irregular building in zone V is presented in which same shear wall with same crossection area is considered which is analyzed by changing the various location to find the optimum position of shear wall for determining the parameters like storey shear, displacement, storey drift and acceleration is done by using standard FEM software ETAB in which beams and columns were replaced by the shear wall.
