Abstract：Due to the frequently happened collisions between over-high trucks and bridge superstructures in urban transport system in last decades, scaled model experiments on the collision between over-high trucks and steel box-section and -section bridges are designed and tested in this work. Corresponding nonlinear dynamic finite element analysis is implemented to simulate the collision experiments. The experiments indicate that even subjected to the same collision load, different bridges have different failure modes obviously. The failure mode of steel box-section bridge is dominated by global deformation, while the failure mode of the steel -section bridge is dominated by the local punching deformation. The simulated results with proposed finite element model agree well with the test results.
