Damage Identification for Simply Nonlinear Structure Using Substructure Isolation Method

摘要：

　　According to thecharacteristics of civil structure, a substructure isolation method for damage identifica tion of simple nonlinear structure is proposed in this paper.The basic idea of substructure isolation method is described as : by using convolution combination of local response, the response of substructure boundary sen sors are constrained to zeros and the sensors are converted to virtual supports, and the substructure is there fore separated from global structure.Inspiring by the idea of conversion from sensor to virtual supports by substructure isolation method, virtual supports are arranged in an appropriate place in simple nonlinear struc ture, then the nonlinear components was isolated from global structure, afterwards, a linear structure was used to damage identification.Finally, this substructure isolation method was introduced and its effectiveness was proved by a plane frame finite element model.
