Pushover Analysis on Plan Irregular Buildings

The generalized non-linear static analysis procedure characterized by use of a static pushover analysis method to represent the structure’s lateral forces resisting capacity is used in this study. For pushover analysis different shapes of building have been considered like square shape, rectangular shape, L shape, T shape, H shape, plus shape and C shape with constant floor area as 900 m2. The capacity spectrum graph is plotted for push x and push y from where performance point is found for each building for 15 storey building and is located in seismic zone five using sap2000 software. The graph is plotted shear force vs. shape of building, displacement vs. shape of building, spectral displacement vs. shape of building and spectral acceleration vs. shape of building and from this the best shape of building is evaluated.
