摘　　要：对结构元件的面积、长度、材料弹性模量和外载均为随机变量的结构系统进行可靠性分析，采用随机有限元法给出失效模式的安全余量。In the paper the reliabilty analysis of structural systems with member cross-sectional area,length and loads,being random variables,adopting stochastic finite element method to give safety margins of failure modes.Using the correlation of safety margins and PNET method,the failure probability of structural systems is calculated.

关 键 词：随机有限元法 安全余量 系统失效概率 可靠性
