基于信息检测条件下的斜拉桥可靠度确定方法研究

Reliability of Cable-Stayed Bridges Based on Information Detection Research on Determination Method

针对斜拉桥的信息检测条件下可靠度评估问题,在原有的β约界法的基础上进行改进,整合有限元法(FEM)、响应面法(RSM)和一次二阶矩法(JC)的相关优势,结合贝叶斯定理,创新性地提出斜拉桥体系可靠度的具体研究方法。

Aiming at the reliability evaluation problem of cable-stayed bridge information detection,this paper improves on the original β reduction bound method and integrates the relative advantages of(FEM),response surface method(RSM)of finite element method and first-order second moment method(JC).Combined with Bayesian theorem,the concrete research method of system reliability of cable-stayed bridge is put forward innovatively.
