| 摘 要： | 利用雷－菲法把非正态变量转换为当量正态变量，建立了在多个任意分布基本变量情况下的可靠性结构优化设计数学模型。该模型以极限状态设计方法为基础，采用机遇约束规划方法变换为一个等价确定性非线性规划问题。最后给出了设计价格最小的矩形截面钢筋混凝土柱的可靠性优化设计实例。

| Abstract: | In this paper,the authors change the abnormal distributed variables into the normal distributed variables by using Rackwits Fiessler method,and obtain the model of the structural optimization design based on reliability standard.This model is based on the limit state design philosophy.This paper adopts the chance constraint programming method and changes the model into an equal deterministic nonlinear design problem.At last,an example of reliability optimization design of the reinforced concrete pillar with the minimum cost is given. |
