摘要
讨论了当把结构的形状参数考虑为随机变量时，平面结构静响应统计特性分析的随机边界元法。利用此法，能计算结构静响应的均值和标准差，估价制造误差引起的结构力学性能的随机性误差。
This paper presents a probabilistic boundary element method for analysis of structural responses to static loads,when the shape parameters of structures are considered as random variables.We can use this method to calculate the mean values and standard deviations of the responses,and estimate the stochastic errors of structural characters resulting from the fabrication errors.
