摘要：This paper analyzed the seismic response of fabricated box girder bridge considering the traveling wave effect based on ANSYS. Take a multi-connected continuous girder bridge over sea island as the research object, consider the effect of pile-soil interaction, the internal force and deformation characteristics of substructure, coping and expansion joint of the bridge are analyzed under the traveling wave effect. Traveling wave effect have some influence on the internal force and deformation of substructure and coping, but the influence is not so strong. Meanwhile the relative displacement of expansion joint and collision force of beam end are influenced significantly, and the risk of girder falling is increased. ?
