摘    要:为对结构损伤进行准确的定位,本文从有限元基本方程出发,将结构损伤程度变量从测点位移列阵中分离出来,从而定义了标志损伤位置的损伤向量,通过求解实测位移列阵与损伤向量的相关系数,可以准确地进行损伤定位。文末算例说明即使在考虑测量误差的情况下本文方法也有很高的准确性。

关 键 词:结构  损伤识别  静态信息  模式匹配法

Abstract:To locate the damages of the structure precisely,in this article,the finite element basic equation is used to separate the variables of the structure damage degree from the displacement matrix of the measure point,so the damage vector which indicates the damage position and can be computed with the deformation of non-damage structure is defined.The damage position can be located precisely through calculating the correlative coefficient of the displacement matrix and the damage vector as Pearson correlative coefficient and comparing magnitude of the correlative coefficient for different elements.Three examples of two numerical simulations and one model examination in the end of this article indicate that this method is very precise considered the measure error and the model error.
Keywords:structure  damage identification  static information  model matching method
