广义随机空间内的一次可靠度分析方法

Method for structural reliability analysis in generalized random space

在广义随机空间内，采用等概率变换原则，提出了一个新的可靠度分析 方法．该法计算过程比较简便，尤其对于相关随机变量的可靠度分析问题，由 于不需要从相关随机向量到独立随机向量的变换，计算上更为简便．分析结 果表明，本文建议的方法和ＪＣ法具有相同的精度．

A new method for structural reliability analysis is proposed in the generalized normal space,by applying the equal-probability-transformation. The proposed method is simple in calculation,and it is much simpler in the case of dependent random variables,because the calculation can be done directly without using the transformation from a dependent random vector to an indepen-dent random vector. Analytic results show that the proposed method has the same accuracy as the JC method.
