【摘要】 本文在广义随机空间内,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．更多还原

【Abstract】 A new method for structural reliability analysis is proposed in the generalized normal space,by applying the equal-probability-transformation.The proposed method is sim- ple in calculation,and it is much simpler in case of dependent random variables,because the calculation can be done directly without using the transformation form a dependent random vector to a independent random vector.Analytic results show that the proposed method has the same accuracy as the JC method.更多还原
