Abstract
The present work deals with analysis of vertical geometric irregular stricture like step building and setback building having stiffness irregularity at different locations. These are analyzed by Pushover analysis. Further from the data obtained from pushover analysis fragility curves are plotted for different damage states for the structure. comparative analysis is carried out. It is found that step building having stiffness irregularity at middle can transfer loads relevantly than when compared to irregularity at bottom. Setback and step building having stiffness irregularity at top may less damaged at initial stage of damages but later gets affected when reaching to extensive or complete damage state concludes they becomes venerable as they get displaced largely.
