曲率模态理论在桥梁损伤诊断中的有限元分析

FEM analysis of bridge damage diagnosis based on curvature mode theory

对基于曲率模态理论的桥梁结构损伤诊断进行了有限元分析,验证了曲率模态对桥梁结构整体损伤、局部损伤都有较好的敏感性,其结论可为实际公路桥梁损伤诊断提供参考。

FEM analysis of bridge damage diagnosis based on curvature mode theory to be studied in this paper. And it is proved that curvature mode is a sensitive index in damage diagnosis for whole bridge structure or for part of it. Some useful conclusions for girder bridge are drawn in this paper and it can serve as references for real bridge damage diagnosis.
