摘要
提出了一种基于实测资料反演力学参数和非侵入式随机有限元法的结构可靠度分析方法,并应用于某重力坝工程实例。通过实测资料反演得到随机变量的均值,而非直接选用设计参数,然后再应用基于随机响应面法的非侵入式随机有限元法进行结构可靠度分析,使随机变量的参数取值更为接近结构的真实运行状态。
A structural reliability analysis method based on monitoring data and non-intrusive stochastic finite element method is put forward, and it is applied to the structural reliability analysis of gravity dams. Before solving the structural reliability, the mean values of stochastic variables can be obtained by the back analysis using monitoring data, which can reflect the performance of structures.
