Abstract
AbstractPresent study assesses the seismic fragility of a set of 4, 8, 12, and 15 storied reinforced concrete (RC) moment resisting frames which were analysed and designed by direct displacement-based design (DDBD) method and performance-based plastic design (PBPD) method. The seismic loads were inculcated in both the methods as per the Bureau of Indian Standards specifications. The seismic performance evaluation of the frames was done by nonlinear static analysis. Damage state thresholds were defined in terms of yield displacement and ultimate displacement to estimate the seismic fragility. Although the seismic performance of both the methods in terms of strength and ductility was found satisfactory, it was observed that the frames designed by DDBD method frames show a lower seismic fragility over PBPD method.KeywordsSeismic fragilityDirect displacement-based designPerformance-based plastic designReinforced concrete moment resisting framesSeismic performance
