Abstract: The objective of the present study is to compare the performance of G+11 multi-storied building. For this purpose five different models of regular, single step vertically irregular, dual step vertically irregular building with and without shear walls are considered. Two different cases of aspect ratio in the geometric irregular frames are considered. In the first case, single step vertically irregular structure with and without shearwall at an aspect ratio(A/L) of 0.28 after third storey in x and y-direction. In second case, dual step vertically irregular structure with and without shearwall at an aspect ratio(A/L) of 0.57 after sixth storey in x and y-direction. In addition to that, the study includes the failure criteria in formation of hinges and behavior of formation of hinges in different structures strengthened with shearwall. In this study Nonlinear static pushover analyses are conducted to study and analyze the structure. The buildings are modeled using ETABS 2017 software and seismic loads are calculated as per IS: 1893-2002(Part-1).
