Abstract:
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.
