Vibration Analysis of Cable-Stayed Bridge under Moving Train

Vibration analysis of cable-stayed bridges under moving railway wagon is described in this paper. The four-axle wagon is modeled by four moving loads having constant relative distance. Two parallel rails of the track are modeled as Euler-Bernoulli beams on elastic points as rail pads. The bridge deck is modeled as a plate supported by some cables. Using this model the effects of wagon weight, cable specifications and lateralposition of train on bridge vibration have been studied
