摘要
文章将基于振动测试的大跨桥梁损伤检测分为 4个阶段 ,介绍了大桥损伤检测中的振动测试和有限元模型建立 ,着重讨论了几种常用的损伤检测方法 ,包括损伤指标法、反分析法、模式识别法和异常检测法 ,并对其进行了比较分析 ;对现有损伤检测方法用于大跨桥梁存在的一些问题 。
In this paper, the vibration based structural damage detection of long span bridges is described as four stages. The vibration measurements and FEM model updating for damage detection are introduced. Some damage detection methods, such as the damage index method,the inverse analysis method, the pattern identification method, and the abnormity detection method, are discussed.Finally, some problems to be solved in structural damage detection of long span bridges are pointed out in the paper.
