摘要
本文提出了一种新的结构可靠性计算方法──响应面法．该法综合运用了多项式拟合、Ｒａｃｋｗｉｔｚ－Ｆｉｅｓｓｌｅｒ法和重点抽样Ｍｏｎｔｅ－Ｃａｒｌｏ法，并可和有限元万法相结合．在求解问题的能力及算法的精度和效率等方面都具有优越性，并且能够求解现有的近似方法不能解决的或不能很好解决的问题，值得在大型复杂工程结构可靠性分析中推广应用．
A new structure reliability analysis method──Response Surface (RS) method is presented in this paper. It is composed of Polynomial Fitting method, Rackwitz-Fiessler method and Important Sampling Monte-Carlo method. Combined with FEM, it is superior to the existing approximate methods in complex structure reliability analysis. Examples show the accuracy and effiency of the RS method with the contest of highly nonlinear and structurally complex reliability problem.
