摘要
基于矩法和加权残值法两者的特点 ,提出了随机结构分析的一种新方法。该法是将加权残值法和概率论中的矩法相结合 ,对随机结构问题进行力学分析和计算。此法简便、快捷 ,且能获得结构各个参数的随机性对结构反应的影响。通过梁和板两算例 ,证明了方法的可行性和有效性。
Based on the features of the method of moment and method of weighted residuals, a new analysis method for stochastic structures is advanced in this paper, in which both the method of weighted residuals and the method of moment in probability were integrated. It can be used to analyze and calculate for the problems of stochastic structures. This method is simple and efficient, and the effect of structural reaction from randomness of each structural parameter can be obtained. The feasibility and validity of the method are proved by the examples of a beam and a plate.
