摘　　要：本文采用概率方法借助于拉丁超立方采样技术和非线性地震反应时程分析对多层住宅砖房的地震易损性进行分析．其分析样本是根据多层住宅砖房目前常用设计参数值的范围选定参数的代表值，并由这些代表值构成的；分析中考虑了地震荷载、结构反应和结构承载力的不确定性．易损性曲线分别对五个不同结构破坏程度的极限状态给出．This paper analyzes the seismic vulnerability of multistory dwelling brick buildings by Latin Hypercube Sampling technique and nonlinear seismic time history response analysis. The representative structures are determined by using some typical parametric values, which are chosen according to the scope of common design parametric values of multistory dwelling brick buildings. In the analysis, the uncertainties of earthquake load and structural parameters are considered. The vulnerability curves are given for five limit states of various structural damage degrees. respectively.
