| 摘 要： | 阐述了利用有限元分析结果进行结构静强度可靠性分析的一种方法。利用工程上较为成熟的一次二阶矩法计算结构单元可靠度，用数值积分法求主要失效模式间的二阶共失效概率，然后采用0Ditlevse的二阶窄边界法计算结构体系的失效概率，最终计算结果与实际相吻合

| Abstract: | A reliability analysis method about structural static intensity was given , which based on the analysis re- sults of finite element. In it, the calculation about united reliablity utilied the Mean Value First-order Second Moment Method, tha calculaion about the probability of two moments inactivating together utilized a kind of numerical integra - tion, the calculation about the structural system inactivation utilized 0. Ditlevsen's Narrow Reiablity Bounds For Struc- tural System , the calculated result was dovetailed with practice. |
