| 摘 要： | 在曲率模态理论基础上,建立一连续桥梁有限元模型,通过计算研究了桥梁损伤的结构动态响应特点,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。

| Abstract: | Based on curvature mode theory used in damage diagnosis,a finite element model referred to a bridge is built in this paper to be studied. Then,the dynamic responses of damaged continuous girder bridge are studied,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. |
