Most of engineering structures is made of all kinds of beam structure element, or, they can be simplified to beam structure, so the main contents of this paper are as following:1. Modal analysis of damaged beam considering boundary conditions.
大多数工程结构都是由梁式结构构件组成的，或者说它们在简化计算时可以看作是简单的梁式结构，因此本文将以梁式结构为基础来研究结构的损伤识别，并在以下几个方面开展了研究工作：1．考虑边界条件损伤梁的模态分析。
