随机结构动力矩阵的线性表示与线性截断

THE LINEAR EXPRESSION AND TRUNCATION OF DYNAMIC MATRIX OF STOCHASTIC STRUCTURES

随机结构地震反应分析是地震工程研究在九十年代的热点课题之一。文中论述了随机结构分析中动力矩阵的线性表示与线性截断方式。本文,提出了虚拟结构方法,为随机结构动力矩阵的形成打开了方便之门。

This paper discusses the linear expression and truncation of dynamic matrix of stochastic structures. A subjunctive structure method is proposed for the purpose of forming the dynamic matrix of stochastic structures.
