摘要
给出了一种计算结构系统刚度可靠度的方法。导出了结构在随机载荷作用下,刚度失效时失效模式的安全余量表达式。用二阶矩法给出了各失效模式的失效概率及各失效模式间的相关系数。用结构系统的可靠性理论给出结构系统刚度可靠度的区间估计和点估计。
A reliability analysis method of stiffness for structural systems is presented in this paper. The safety margin expression of the failure modes is drvived when the structure fails on stiffness under random loads. Using the second -moment reliability analysis, the failure probability of failure mode and the relative coefficient between the failure modes are presented. Based on the reliability theory of structural systems, the bound estimation and point estimation of the stiff- ness reliability are given in the paper.
