Finite element Simulation of Truck Impacts on Highway Bridge Piers
Recent studies show that the dynamic forces because of truck impacts may be significantly higher than the 600kips force recommended by the AASHTO. Hence, there is a need to carry out detailed investigations on vehicular-bridge collision for a reliable evaluation of an existing bridge subject to impact by trucks and design of new bridges with more redundancy for vehicular impacts. In this research, an extensive investigation on the impact of a three-span steel girder bridge with reinforced concrete piers by a medium weight truck running at different speeds has been carried out using finite element models of bridge and the truck in LS-DYNA. The performance of the critical highway bridge components during vehicle collision and the factors causing damage/failure of the typical bridge components have been identified.
