Abstract

In this paper, the dynamic response analysis of long-span continuous bridge under earthquakes and train loadsimultaneously were performed. In order to considerthe coupled vibrations of vehicles and highway long-span continuous bridge, a numerical modelinvolving soil foundation under inclined seismic wave was established using finite element software. The dynamic response ofthe bridge withdifferentincidenceangles of seismic waves and the differenttrain speedswere calculated and analyzed.The results show that seismic waveincident angles have a significant effect on the dynamic responseof the bridge, and with the increasing of the incident angle, thevertical displacements, velocity and accelerations of mid-spanconstantly increase. While thetrain speeds have a slightly effect on the dynamic responseof the bridge under earthquake, and the dynamic responseof the bridge reach maximum at a certain speed.
