Vulnerability of Bridge Piers to Impact by Heavy Vehicles
My talk presents work undertaken to investigate the effects of vehicle collision on bridge piers. Inelastic transient finite element simulations are used to investigate the structural demands on bridge piers generated during such events, which have occurred in the past, sometimes with catastrophic consequences. Two different types of trucks and two different bridge/pier systems are used in the simulations. The approach speeds for the trucks range from 55 to 135 kph. Various quantities of interest are extracted from the finite element results and used to develop a better understanding of the vehicle/pier crash process and to critique current specifications addressing such events.
