Abstract:The seismic vulnerability of existing structures was studied. Considering the fact that the residual life is usually shorter than the reference period, the parameters of earthquake action at various re-service term are given based on the equal exceeding probability principle. Firstly, the impact of different soil conditions on ground motion parameters was analyzed, and the stochastic time-dependent characteristics of resistance were taken into consideration, then the seismic ground motion parameters were adjusted. Furthermore, using these parameters the seismic vulnerability analysis of existing structures was done based on the probability Pushover analysis. The results show that the failure probability of structures increases with the decrease of residual life.
