中文摘要：

在大多数情况中，一本参考书为 structuralhealth 诊断是必要的，是众所周知的，并且为给定的结构获得如此的一本参考书是很困难的。在 thispaper，一个氏族成员信号方法(CMSM ) 在由组组成的结构为使用被建议(或氏族) 有一样的几何学，即，一样的生气的节和长度，和 identicalboundary 条件。在 anevent 以后在一个氏族在任何 undamaged 成员上测量的信号能在氏族为任何另外的成员被用作引用，这被期望。验证 applicabilityof 建议方法，钢捆绑模型被测试，结果证明 CMSM 是在在由相同苗条成员组成的结构检测本地损坏的 veryeffective。

英文摘要：

It is well known that in most cases, a reference is necessary for structural health diagnosis, and it is very difficult to obtain such a reference for a given structure. In this paper, a clan member signal method （CMSM） is proposed for use in structures consisting of groups （or clans） that have the same geometry, i.e., the same cross section and length, and identical boundary conditions. It is expected that signals measured on any undamaged member in a clan after an event could be used as a reference for any other members in the clan. To verify the applicability of the proposed method, a steel truss model is tested and the results show that the CMSM is very effective in detecting local damage in structures composed of identical slender members.
