Fragility Analysis of RCC Frame Structure

In recent years, number of studies have been carried out for the evaluation of vulnerability of structure during seismic events. Fragility analysis is one of the important probabilistic approach to estimate the damage data at different damage state during seismic events. The G+10 Reinforced Concrete frame structure is considered for analysis. The structure is analysed in ETABS by Incremental Dynamic Analysis. Fragility curve developed for Incremental Dynamic Analysis for different damage states by considering set of 3 real ground motions. The fragility curves are derived from analytical method. The fragility points for different damage states are derived from analytical formula. From Incremental Dynamic Analysis fragility curve plotted for probability in Y-axis and peak ground acceleration in X-axis for five different damage state. The behaviour of fragility curve after achieving the 100% probability for different damage state is constant.
