摘要
本文提出一种结构随机分析的Monte Carlo加权残值法。文中建立了这种方法的基本列式,并通过静力挠度、固有频率和屈曲荷载等算例,表明本文方法理论简捷,计算工程量少,精度较高,是随机结构数值分析的有效方法。
In this paper,the authors have put forward the weighted residual method by Monte Carlo for random numerical Analysis of structures,and have derived the formulas of this method. Analysis of statical deflection,natural frequency and buckling load are given as examples. The results show that the proposed method is clear in concepts and simple in calculation, and has a relatively high accuracy. It is much effective method for random numerical analysis of structures.
