Abstract:
The 30 m span prestressed concrete prefabricated box girder bridge was taken as study example to evaluate the working performance of bridge under vertical impact(heavy dropped cargo, rockfall). The refined finite element(FE)model of bridge structure was established and also verified by full-scale model test results. The dynamic response and damage evolution of multi box girder bridge was investigated by explicit dynamic analysis under dropped cargo impact. The damage feature and mechanism of the bridge were analyzed under different impact positions, energies angles of dropped cargo. The results show that the impact load will lead to both overall and local damage, and the damage process can be classified into three stages, including initial impact stage, damage progress stage and final stable stage. The impacted girder suffers more severe damage, and the displacement and reaction force increase significantly as that the impact position moves from middle girder to side ones. As the impact position transfers from mid-span to support end, the damage pattern of the impacted beam varies from flexural failure to shear failure, and the displacement and support reaction decrease as well. As the impact energy increases, the impacted girder exhibits more severe damage while the non-impacted girder is less influenced, and the rebar stress, impact force, reaction force and displacement of the impacted girder also significantly increase. The longitudinal rebar yields when the impact energy exceeds 391.9 kJ. The impact contact area varies with the cargo falling angle. The damage range, reaction force and vertical displacement reduce significantly if the cargo contact area decreases, whereas the local damage is more severe. The impact parameters of dropped cargo have great influence on the bridge damage, and the corresponding reinforced maintenance measures should be adopted according to the specific damage characters.
