Effect of Shear Wall Shape on Seismic Response of RC Building Frames

This paper presents the effect of shape of shear wall on seismic response of a nine-storey moment resisting RC frames using non-linear static (pushover) analysis. The moment resisting RC frame is rectangular in plan and shear walls are provided along the least lateral dimension of the building plan. Different shapes of the shear wall (e.g., S, B, C, H and E) have been used in the analysis. The building frame along with shear walls has been modelled using FEM software SAP2000 and seismic responses of the building frames with different shapes of shear wall has been measured in terms of pushover curve (performance point, storey drift, top displacement and base shear). It has been observed that maximum performance level of building frame occurred when the shear walls are provided with S-shape.
