| 摘 要： | 本文介绍了一种用于结构可靠性分析的随机有限元法，用它来计算结构响应变量的各阶统计矩，结合ＪＣ法和一次二阶矩法对一卒砼坝坝体了可靠性分析，计算出其可靠性指标及失效概率。该法与其它方法比较有计算快捷、精度较高的优点。该法已经用ＦＯＲＴＲＡＮ语言编制成适用于在微机上计算的程序。

| Abstract: | In this paper, a stochastic finite element method for the analysis of structural reliability is presented, The statistic moments of response variables can be easily carried out by using this approach. In combination with JC method, the reliability and failure probability of one concrete dam are calculated, The result obtained by this method is in good agreement with Monte Carlo method, but it is more efficient than Monte Carlo method. |
