摘要
阐述了曲率模态参数的特性,从有限元动力响应基本原理出发,分析了曲率模态用于识别桥梁结构损伤的机理,说明了曲率模态是一类对结构局部变化有敏感性的动力学参数,对于进一步在实际工程中识别桥梁结构损伤行为具有重要的指导意义。
The characteristics of curvature modal parameters are analyzed and discussed in detail. Some basic formulae are deduced based on the dynamical responses principle of FEM and curvature modal parameters are found to be a kind of dynamical parameters which could identify the damages of bridge structures and be sensitive to the local deformation. All these should be of importance for the damage identification in bridge structures.
