摘要
提出一种迭代格式的响应面方法,以模拟实际工程中常见的功能函数不能明确表达的极限状态曲面.结合结构可靠度分析中的几何法,可直接应用现有的确定性的结构分析程序,对大型结构进行可靠度分析.数值结果表明本文方法具有较好的效率和精度.
In this paper, an iterative response surface approach is proposed to simulate the closed-formed limit state surface in actual engineering. In conjunction with the geometric method in structural reliability analysis, the deterministic structural analysis programs such as SAP5 can be used without modification to solve the probability problem in large complex structural engineering. Analytical results show that the proposed method has good efficiency and accuracy.
