结构动力可靠度的模糊化方法
|
摘要
从新的角度认识结构模糊动力可靠度，提出了直接从非模糊可靠度出发，获得模糊可靠度的方法，考虑了所获公式在不同界限和结构类型问题中的形式；讨论了模糊可靠度的性质；比较了直接采用模糊数学方法和模糊化方法所得结果的异同；给出了便于实际应用的简化计算公式，及其在三峡大坝可靠性分析中的一个应用实例
In the paper, the structural fuzzy dynamic reliablity is consided from a new point of view A new method, which start directly from the unfuzzy reliability, is developed to obtain the fuzzyreliability The forms of the formulas gained with the method are discussed for various bounds and structural types Some proporties of the new fuzzy reliability are demenstrated Some differences between this mothod and others with normal fuzzy mathematic methods are pointed out Some simplified formulas, followed by an application, are suggested
