An　implicit　integration　finite　element　model　and　an　explicit　integration　finite　element　model　were　established　to　simulate　the　seismic　responses　and　failure　modes　of　a　cable-stayed　bridge　model　with　single　tower　in　shaking　table　tests.　Then,　according　to　the　implicit　integration　finite　element　model,　the　influences　of　the　traveling　wave　effect　and　the　tower-cable-girder　coupling　vibration　on　the　seismic　responses　of　the　cable-stayed　bridge　with　single　tower　were　analyzed.　The　results　show　that　the　implicit　integration　finite　element　model　can　simulate　the　seismic　behaviors　of　the　cable-stayed　bridge　with　single　tower　before　failure.　The　explicit　integration　finite　element　model　can　predict　whole　the　failure　process　of　the　cable-stayed　bridge　with　single　tower　under　strong　earthquake.　The　influences　of　the　traveling　wave　effect　on　the　seismic　responses　of　the　cable-stayed　bridge　with　single　tower　are　different　due　to　the　difference　of　frequency　spectral　characteristics　and　wave　velocities.　Under　strong　earthquake,　tower-cable-girder　coupling　vibration　occurs,　leading　to　the　significant　increase　of　the　longitudinal　displacement　response　of　the　main　tower.　©,　2015,　Southeast　University.　All　right　reserved.
