The vibration-suppressed effectiveness of semi-active control and passive control for a long-span floating cable-stayed bridge is calculated and analyzed with its three dimensional finite element model. The seismic responses of cable-stayed bridge under traveling wave input are calculated. Semi-active control and passive control can get good control efficiency for the most seismic responses of the cable-stayed bridge, but they can make some seismic responses including axial force of the beam lager. The seismic inputs with different frequency spectrums evidently influence seismic responses of the cable-bridge and vibration-suppressed effectiveness of the control methods. Semi-active control is better than passive control with most damping force all along for vibration-suppressed effectiveness of the integer seismic responses after traveling wave effect considered. Traveling wave effect can make bad influence on the beam of cable-bridge, but can be propitious to bridge tower. Bad influence of traveling wave effect on vibration-suppressed effectiveness of the two control methods is not remarkable.
