Abstract:

Fragility analysis is simply vulnerability assessment of buildings subjected to seismic motions. In this analysis, seismic fragility curves are derived with the help of non-linear dynamic analysis of the building. These curves define the conditional probability which exceeds a particular limit of failure and evaluate the seismic vulnerability of the structure and this probability of failure is a function of ground motion intensity. This paper deals with literature review of different authors on fragility analysis, incremental dynamic analysis method and ground motion intensity measures. The object of this study is to evaluate the fragility curves by incremental dynamic analysis method for a G+6 storied hypothetical model of existing RC building which has a practically more relevant plan having plan and vertical irregularities.
