三维结构可靠度对随机变量的敏感性研究

SENSITIVITY ANALYSIS OF 3-D STRUCTUAL RELIABILITY TO RANDOM VARIABLES

摘要: 本文基于三维随机有限元提出了结构点可靠度、失效模式的可靠度及整个结构体系的可靠度分别对随机变量的“分布参数”和“极限状态方程参数”的敏感性计算方法,并以一典型重力坝为例进行了计算,得出了若干有益的结论。

Abstract: Based on 3-D SFEM, sensitivity (including distribution parameters and limit state function parameters) analysis of component reliability and failure mode reliability and whole system reliability is presented. A standard gravity dam taken as an example, some useful conclusions are given.
