摘要
本文对向量值和矩阵值函数的不确定结构的静力响应和可靠性进行了研究。基于Ｋｒｏｎｅｃｋｅｒ代数和摄动理论导出了随机结构的有限元分析方法，随机变量和系统导数很方便地排列到２Ｄ矩阵中，给出了一般的数学表达式．
This paper studies the static response and reliability of uncertain structures with vector-valued and matrix-valued functions.The finite element analysis method of uncertain structures is based on matrix calculus.Kronecker algebraand perturbation theory.Random variables and system derivatives are conven- iently arranged into 2D matrices and generalized mathematical formulae forprobabilistlc perturbation are obtained.
