| Abstract: | The speedway skew bridge is easily destroyed in earthquake and it's necessary to study on seismic design.The method of space beam gird was adoptde in building finite element model of the speedway skew bridge.The bridge is one of the middle route south-to-north water transferring project.Response spectirum theory is applied in earthquake numerical simulation.Further more,deformation and internal force of the bridge was checked.Through the results of structural seismic check analysis,some effective aseismic m... |
