工程结构模糊失效模式的优化准则法

基于枚举结构静强度主要失效模式的优化准则法，利用关于随机和模糊熵的定义，建立了模糊随机变量向等效的随机变量的转换关系。把这种关系用于建立模糊随机结构失效模式得到了较好的效果。并用算例来说明这种方法的应用和有效性。对于大型结构，结合并行计算方法，将会使计算时间大大地减少。

Optimality Criterion of the Significant Failure Modes of Engineering Structures

Basedon the enumerate significant failure modes on general reliability of structure static strength,using the entropy concept,a relationshipbetween a random fuzzy parameter and an equivalent random parameter is presented. With the relationship, it can be made good result on the failure models of the random fuzzy structures, and an example is given to show the availability and advance of the new method. Finally, after discussed the steps of the optimality criterion, it is pointed out that if combined with the parallel computation, the algorithm will be more efficiently.
