考虑地震动和结构物理参数不确定性，提出一种基于响应面法的层间隔震结构地震易损性分析方法。以中心复合设计方法建立地震动-层间隔震结构样本，对系统样本模型进行非线性动力时程分析，分别建立层间隔震结构各子结构的响应面模型，在此基础上采用蒙特卡洛模拟获得易损性曲线。分析结果表明，提出的方法计算量少、精度高，有效提高了易损性分析作为层间隔震结构性能评估的时效性，具有较大的工程应用前景。

Considering the uncertainties of ground motions characteristics and structural parameters,a fragility analysis method of inter-story isolation structures based on RSM(response surface method)was proposed.Using the central composite design method to construct a series of samples for various ground motions and inter-story isolation structures,nonlinear dynamic time-history analyses of the sample models were performed,and then the substructure response surface models of an inter-story isolation structure were built.Its fragility curve was obtained with Monte Carlo simulation method.Analysis results showed that the proposed method has less amount of calculation,and a higher accuracy to effectively improve the efficiency of a vulnerability analysis,and it has engineering application prospects.
