Dynamic Response of a Steel Bridge under Earthquake Action in Liugong Island of Weihai

Abstract:

This study presents finite element analyses for a special steel bridge under the action an actual seismic wave. The maximum stress and the maximum deflection of the bridge are calculated based on the dynamic analyses. It is found that the bracing system and the beams between the two columns at the end of the bracing system are the critical members in the steel bridge under seismic action. The maximum displacement of the steel bridge is located at the overhang beams at the bridge end. However, the dynamic response is different when the seismic wave is input in different directions. Based on the numerical results, it is found that the special steel bridge is safe under the seismic action.
