Abstract

Abstract

Compared with displacement mode,strain mode is better in steel truss damage detection.A new structural nondestructive detection indictor,a dynamic and static combining indictor is presented,which is based on dynamic indictor and static indictor.The new indictor has advantages of method of dynamic and static.It can filter much effect of non-damaged elements.It is much exact than only used dynamic and static indictor for damage detection.Then its availability is verified through a steel truss numerical simulation,and by comparing with dynamic and static detection indictors.The result shows that new indictor is the best.Furthermore,the second-detection and repeated detection methods are presented to solve shortcoming of little strain is difficult to detect in different kinds of components' damage in numerical example.
