Prediction of lateral impact loads imparted to bridge piers during barge collision events

摘要

In order to quantify and characterize the loads imparted to bridge piers during barge collision events, nonlinear finite element impact simulation has been employed to simulate a variety of different vessel impact conditions. Descriptions of the methods used to model a hopper barge, bridge piers, and soil-structure interaction are given. Impact simulation results, including impact loads and barge deformations, are presented and compared to data generated using currently accepted bridge design specifications.
