Shear wall has high in plane stiffness and strength which can be used to simultaneously resist large horizontal loads and support gravity loads. For the buildings on sloping ground, the height of columns below plinth level is not same which affects the performance of building during earthquake. Thus to improve the seismic performance of building on sloping ground the shear walls play very important role. Hence in this study the attempt is made to analyse the multi-storey buildings on plain and sloping ground with and without shear walls. The performance of the building with various configurations of shear walls such as straight, L shape, T shape and channel shape is studied. For all shear walls configurations under considerations the length of shear wall in two principal directions in plan is kept equal. The RCC building models having G+6 storeys with shear walls and without shear walls resting on plain and sloping ground (slope 1V:2.33H) are considered for the study. The response spectrum analysis of building is carried out using structural engineering software SAP 2000 V 15.2.2 and the seismic performance of building with various shear walls configurations is compared with respect to parameters like base shear, lateral displacement, time period and member forces.
