Collision Loads on Bridge Piers

Researchers at the Center used worked on providing an estimation of the dynamic force of an errant heavy vehicle upon impacting a bridge pier using simulations methodology.  Simulation was also used to design the experimental setup to confirm the finite element prediction of the impact force. Extensive simulation cases were conducted using full scale model of a tractor trailer truck and a heavy single unit dump truck.
