Abstract: In the present era, tall buildings are very much prominent, therefore its safety against earthquake forces is of vital importance. Shear wall provides an excellent means of resisting the earthquake forces by resisting the lateral force occurring on the building. To provide desired amount of strength and stiffness shear walls are used in the buildings. However, positioning of shear walls requires due consideration both in symmetrical and unsymmetrical buildings. In symmetrical buildings the center of gravity and the centre of rigidity coincide, so that the placement of shear walls is symmetric along the outer edges or inner edges of building. Therefore, it is necessary to find the most ideal and efficient position of shear wall to minimise the effect of torsion. The work presented in this paper focuses on the performance of various geometries of shear wall namely: C-shaped, L-shaped, I-shaped, Rectangular-shaped. In this study G+6, G+16 and G+25 storeyed building is modelled and analysed for lateral displacement, storey stiffness, storey drift using ETABS-2016 software. The analysis of the building is done by using equivalent static method and the results obtained from this method are plotted graphically.
