中文摘要：利用结构单元刚度矩阵的特征值分解和组合,获得结构总体刚度矩阵的分解表达式。以结构刚度矩阵的分解式为基础,推广并改进基于特征值分解的结构损伤识别方法,以一个梁结构为例验证所提方法的可行性。

外文摘要：With the increasing demands for structural quality and reliability,damage identification via techniques that examine changes in measured structural vibration response is a very important topic of research.The damage detection methed based on the eigenvalue decomposition is improved by using a universal matrix disassembly technique.A new matrix disassembly technique is proposed firstly in respect that the previous disassembly techniques are all complex and not fit for program.In the presented approach,the di...
