Simplified analysis of longitudinal stiffened plates in a continuous steel box girder bridge

摘要

This paper investigates the thin-walled box girder bridges with large width-to-span ratios through both experimental and numerical studies. For the complexity of the bridge, different discrete models are presented in the analyzing of the longitudinal stiffened plate. In addition, a large-scale Plexiglas model is tested under different loading cases. The simplified simulation of the computation results compared well with the experimental results. It is illustrated that it is an effective method to predict properties of this kind of bridges.
