摘要
本文把边界元的灵敏度分析与摄动法相结合．提出了随机边界元法．利用这种方法，可以计算结构响应的均值和标准差，估计由于材料特性Ｅ、ｖ的不确定性导致的响应误差．
In this paper,a probabilistic boundary element method by combining the perturbation technique with boundary element on the basis of design-sensitivity analysis is presented.By using this method,one can calculate the expected values and standard deviations of structural responses,and estimate the errors of structural responses caused by measurement errors of E and v.The applications of this method in reliability analysis for structures are also discussed.
