| 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. |
