摘　　要：介绍残余力向量法的基本理论,提出识别框架结构损伤的方法。以某个损伤工况已知的框架结构为例,计算识别其损伤情况。研究表明,只需损伤结构的一阶模态即可识别结构损伤情况,且该方法的有效性通过对比分析得以验证。This paper mainly introduces the basic theory of residual force vector method and the method which isused in identifing frame structure＂ damage. Taking a damaged frame structure as an example, it can identify thecondition of the damage. The results show that can identify structural damage condition by the first modal, and theeffectiveness of this method have been verified.
