Abstract

Abstract

To investigate the dynamical responses and failure behaviors of prefabricated reinforced-concrete (RC) box-girder flyovers caused by collision of over-height vehicles, a recent actual engineering accident is taken as an example to carry out refined numerical analysis by the finite element method, and a double mass-parallel spring (DM-PS) simplified vehicle model is proposed to effectively simulate the eccentric collision between the over-height vehicle and bridge superstructures. The effectiveness of the proposed DM-PS model is fully assessed through comparison with two widely-employed vehicle models, i.e., a full-scale (FS) model and a simple rigid (SR) model. The comparisons display that the failure characteristics of the collision area can be obtained by using the FS model, which is basically consistent with the photos of the accident scene; the SR model overestimates the local damage of the structure and underestimates the overall structural deformation; while the DM-PS model has high accuracy for predicting the structural failure. Therefore, the proposed DM-PS model can provide a simple and effective analysis tool for the protection design of bridge structures subjected to over-height vehicle collision. On this basis, a detailed parameter analysis of the structural behaviors is carried out by the DM-PS model, and the effects of vehicle collision velocity, mass, position, and structural form are investigated in depth. It is shown that the structural sensitivity of the impact dynamic behavior to the collision velocity of the vehicle is significantly greater than that of the collision mass of the vehicle; the deformation and failure modes of mid-span collision and side-span collision are quite different, and the damage of side-span collision to one side base is more serious; the box plate and reinforced plate in the box girder can effectively improve the structural impact resistance. Numerical results and conclusions can provide a reference for the crashworthiness design of bridges. The critical information of the finite element analysis process is presented in detail.
