Vehicle-Induced Dynamic Response of Expansion Joints in Long Span Bridges

Abstract:

Due to increasing traffic on long span bridges, behavior of expansion joints is believed to be largely influenced by pounding impact from passing vehicles. In order to precisely understand behavior of expansion joint under vehicle impact loading, a new analysis scheme is proposed which incorporates interaction between vehicle and expansion joint. Mathematical model of vehicle is established and solved with Newmark method. Expansion joint is modeled with refined solid element in Finite element software ABAQUS. The analysis indicates that vehicle loading can induce large dynamic response of expansion joint in long span bridges.
