| Abstract: | The finite element model and seismic mitigation control dynamic simulation model were established for curved continuous bridge with double supports.According to the arrangement of bearings of continuous bridge,eight magnetorheological dampers were set in the tangent orientation at active bearings.Three ground motions with different spectra were input in the longitudinal direction of curved bridge.Seismic mitigation effectiveness of seismic active control,semi-active control and passive control for curved co... |
