| 摘 要： | 本文以模糊随机变量为基本变量，定义了结构的模糊随机功能函数，分析了结构有效状态与失效状态之间的模糊性，建立了结构的模糊随机极限状态方程。利用序关系给出单失效模式结构的模糊安全准则，讨论了ａ－约束水平条件下单失效模式结构的失效概率、可靠度及可靠指标，进而得出结构的模糊随机失效概率、模糊随机可靠度及模糊可靠指标等。本文给出的具体计算方法和目前设计规范中彩的方法是相对应的。

| Abstract: | In this paper using fuzzy random variables as basic variables we define a structural fuzzy random failure function and analyze the fuzziness between structural effective state and failure state. A structural fuzzy random limit state equation is established. Using order relation,a structural fuzzy safety criterion of single-failure mode is given. Structural failure probability reliability and reliability index of single failure mode are discussed under a-constraint level. And then structural fuzzy random failure probability fuzzy random reliability and fuzzy reliability index are obtained. The practical calculation method given in this paper is corresponding with current Design Code. |
