dc.description.abstractDamage detection is the core technique of structure health monitoring systems. Mostly, the detection is based on comparison of initial signatures (frequency, mode shapes and so on) of intact structure with that of damaged structure. The techniques based on the analysis of vibration data of structures have received great attention in recent years. Generally, high-rise buildings have enough security under wind or some other natural conditions. Instances of damage caused by routine work can be rarely found. But under earthquake, high-rise buildings damages may occur on some weakness areas. In this paper, based on establishing the stiffness matrix of the columns and beams with joint damage, the finite element model of the damaged frame structure is set up. Calculating the modal date by the finite element model between the intact and damaged structure, simple and multi damages being imitated at the locations of the joints, the curvature mode shape method is used to identify the damage. The numerical example shows that the structural damage can be efficiency identified by using vibration characteristics of the building.zh_CN
