摘要
文章概述了桥梁有限元模型修正方法的一般原理以及主要方法,传统的有矩阵型修正法、以灵敏度分析为基础的动力模型和静动力模型修正法,还介绍了近年发展较快的以统计理论为基础的基于响应面的有限元模型修正法。同时,文章分析了这些方法的优点和不足之处,最后就目前研究中尚未解决的问题作了一些探讨。
This paper summarizes the general principles and main methods of the bridge finite element model correction method. The traditional correction methods include the matrix correction method, the dynamic model correction method and the static and dynamic model correction method based on sensitivity analysis. Besides, The finite element model correction method based on response surface, which has developed rapidly in recent years and based on statistical theory, is also introduced. At the same time, it also analyzes the advantages and disadvantages of these methods, and finally discusses the problems that have not been solved in the current research.
