| 摘 要： | 根据结构可靠指标的几何意义，建立了正态随机变量和非正态随机变量下的结构可靠度计算的优化模型，并利用已有的优化方法对其求解方法进行了研究。本文的方法无需对非线性功能函数作线性化近似处理，从而提高了结构可靠度的计算精度，扩大了其适用范围，为结构可靠度分析提供了一种新的思路。

| Abstract: | IOn the basis of the geometrical meaning of structural reliability index, an optimum model for structural reliability analysis under conditions of normal random variables and abnormal random variables is established. Taking advantage of the existing optimum methods, a solution for the optimum model is proposed. The nonlinear performance function needs not be lined by the proposed method, which improved the accuracy of reliability calculation and extended its suitable range, and a new means for reliability analysis is provided. |
