| 摘 要： | 对在役结构进行了易损性分析.考虑后续使用期往往小于实际基准期的事实,依据等超越概率原则给出不同后续使用期内地震作用参数的具体取值.首先分析了场地土对地震动参数的影响,在此基础上又考虑了抗力的随机时变性,然后利用调整后的地震动参数对在役建筑物进行基于概率Pushover分析的结构易损性分析,得出结构在不同的地震作用下,结...

| 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... |
