摘　　要：在结构系统的可靠度计算过程中,当随机变量为相关的非正态分布时,利用正交变换或Rosenblatt变换计算其可靠指标,计算量较大。采用在广义随机空间内计算各机构可靠指标,然后利用PNET法计算结构体系可靠度,计算简便,精度也满足要求。In calculations for structural system reliability, when random variables is non - normal distribution, it is a heavy workload to calculate the reliability index in terms of orthogonal transformations or Rosenblatt transformations. It is suggested that the reliability index of each individual mechanism be calculated in generalized stochastic space, and then structural system reliability be calculated in terms of PNET. As a result, calcu- lations become simple and accurate.
