| Abstract: | In this paper,based on an interchange ramp project and by using large-scale structural analysis program Midas/Civil,a finite element model is built in view of the particularity of curved beam bridge.The dynamic time history analysis method is used to study the critical seismic response of curved beam bridge with horizontal and vertical actions.The results indicate that the center of bridge bearing and the vertical direction are the worst-case input directions of horizontal seismic shock.The vertical seismic... |
| Keywords: | curved beam bridge critical angle of horizontal seismic action vertical seismic action plane of weakness time history analysis |
