The Analysis of Barge Bridge Collision Response

Barge collisions with bridge piers are frequent accidents that may result in intensive damage, even the collapse of bridges. Due to the difficulty and high expected cost of model testing, this study will use a finite element simulation tool to perform collision analysis. This study investigates the structural behaviour of an impacting barge against a single square and circular bridge piers. The barge and bridge piers are modelled by using a nonlinear finite element model (FEM). The body of the barge and both the bridge piers are assumed to be rigid. The detailed numerical model of the barge and bridge piers is modelled in the Abaqus software. Impact results were obtained at different collision positions to show the consequences of the bridge piers and barge damage. Thus, the kinetic energy, impact force–time, impact force–deformation relationship of the barge are established based on the model results of the impacted structure.
