Paper Abstract

The precise evaluation and improvement of the bearing capacity of actual existing bridges mainly depend on the accurate baseline finite element model (FEM) of structures. The FEM updating technique is an effective way to obtain the accurate FEM of bridges by minimizing the differences between the measured and analytical features of structure. In this study, the FEM updating technique is implemented to obtain the baseline FEM of a practical bridge oriented to the bearing capacity improvement. Firstly, the detailed damages of this actual bridge were investigated by visual inspections, and the static and dynamic structural characteristics were obtained by carrying out the loading tests. Secondly, the updating parameters were determined by considering the practical damages of this bridge. Finally, the baseline FEM of this bridge, considering the stiffness reduction of structure, was obtained by using the measured structural characteristics. The generated baseline FEM is suitable for the stiffness strengthening of this bridge.
