摘要
从三个方面:(1)基于模型修正理论的结构损伤识别;(2)损伤指数法;(3)人工神经网络法等,对近年来国内外基于振动分析和结构动力学参数的结构损伤识别理论进行了比较系统地总结和评述,介绍了结构损伤识别领域研究的现状,给出了基于动力学参数和振动分析的结构损伤识别的模式,并分析了存在的困难以及需要进一步研究的问题.
This pape ture damage identific three ways as follows （3） artificial neural r systematically summarizes and reviews the problems and achievements for bridge strucation, which are found based on vibration analysis and structure dynamic parameter from ： （1） Based on finite element model refinement theory, （2） Damage index methods, network. The current state of the damage identification technology as well as the pattern for damage identification based on vibration analysis is presented in this paper. The current difficulty and the problem for future research in this area are also presented lastly.
