| 摘 要： | 结构可靠度指标是结构可靠度分析的关键.本文在分析结构可靠度模糊性的基础上,首先指出结构失效破坏是一个模糊随机事件,并给予模糊可靠度指标β_1和初指标β?的定义,同时导出β_1的近似计算公式,最后以佛子岭连拱坝观测资料为例,说明模糊可靠度的分析方法.

| Abstract: | The target of structural reliability is the key of reliability analysis of structure. This paper based on the fuzziness of structural reliability analysis, first points out that structural failure is a random and fuzzy event. Then proposes the definition of fuzzy reliability target and derives its approximate calculative formula. Finally, the prototyoe observational data of Fuziling Muiti-arch dam is used, as an example to explain the analytic method of fuzzy reliability. |
