Finite Element Model Updating of Existing T-Girder Bridge by Field Quasi-static Generalized Influence Line

摘要：

　　Finite element model updating is the important foundation of structural damage detection, condition assessment for engineering structure.A new method, for finite element model updating based on the quasi-static generalized influence line (QSGIL) residual objection, is presented to update the finite element model of beam-structure in order to improve the quality and precision of finite element analysis.Both of the theory and model experimental study show that the proposal method can efficiently update the finite element model in the previous study 1.In this paper, the updating techniques are further developed to update the finite element model of the existing T-Girder bridge, the QSGIL of the updating model agrees very well with the field QSGIL of the existing bridge, which illustrates that the proposal methodology is promising in the practical bridge structure and other structures.
