摘要
本文假定随机变量呈正态分布，采用一阶摄动建立了适合工程结构可靠性分析的随机有限元方程，具有对原始数据采集要求低、程序设计简便、可充分利用通常的有限元结构分析成果等优点。
The stochastic finite element equation for reliability analysis of engineering structures is proposed. In this paper the assumption of normal distribution of random variables and the first order pertubation method are adopted. This method has many advantages. The achievement of general finite element analysis can be made use of. The programme design and digital sampling are very simple.
