| Abstract: |
| In this paper, the uncertainty structures are described by the fuzzy variables. Based on the fuzzy interval analysis and the non-probabilistic reliability method provided by authors, a theory of fuzzy reliability for mechanical and structural systems in the possibility context is established in this paper. An independent fuzzy index of reliability possibility and a measure of failure are proposed to measure the safety of fuzzy structures or systems. The developed procedure is easy to implement, and some more useful information can be offered for the evaluation of structural reliability. A numerical example is given to illustrate the applicability and effectiveness of the proposed procedure. |
