摘要/Abstract

摘要： 论述了曲率模态分析的基本理论，探讨了曲率模态在结构损伤检测中的应用，并举例证明了曲率模态方法具有良好的准确性，灵敏性

关键词: 桥梁损伤检测, 模态参数, 曲率模态

Abstract: Considering that curvature mode shape can identificate the damage of sturctures and locate it．the theoretical basis of curvature modal an alysis is discussed emphatically in the paper．And considering that curvature mode shape can identify the damage of structures much sensitive，the theoretical basis of curvature modal analysis is discussed emphatically in the paper． The plications of curvature modal analysis in which should be regarded in the actual and conclusion are given．

Key words: damage detection for bridges, modal parameter, curvature mode shap
