Finite Element Model Updating Based on Field Quasi-static Generalized Influence Line and Its Bridge Engineering Application

Abstract 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 in order to improve the quality of finite element algorithm. The experimental study shows that the method can efficiently update the finite element model.
