Multi-Scale Finite Element Models in Bridge Field Tests
We used multi-scale finite element model (FEM) to give better predictions of bridge mechanical behavior in field tests. A multi-scale FEM of the overall bridge was developed based on practical bridge engineering and its accuracy was verified by the traditional beam element model. The multi-scale FEM was divided into the unconcerned segment and concerned segment. The concerned segment of the bridge girder was built with the solid elements to improve analysis accuracy. The unconcerned was built with the beam elements to save on analysis costs. The comparisons among the FEM results and field test shown that the multi-scale FEM was especially suitable for the bridge field test. This type of model can give precise predictions on the stress distribution and flexural stiffness of the tested bridge.
