| 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。

| Abstract: | 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 relia- bility 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. |
