摘　　要：通过考虑结构体系内部各个可能失效机构之间的相关性,以及单个机构失效对整个结构体系失效的影响程度,并把这两方面结合起来,提出了一种计算结构体系可靠度的概率权重法。通过与PNET法和MonteCarlo法的计算结果进行比较,证明了这种方法的可行性。A probability-weighing approach for calculating the reliability of structural system is worked out by taking into account of correlation among various possible failure mechanism in the system, as well as the effect of a single mechanism failure on the failure of the whole system. The comparison of the results from PNET and Monte Carlo indicates its feasibility.
