Coupled Vibration Analysis of Bridge Deck and Cable of Long-Span Cable-Stayed Bridge

  • Received Date: 19 Mar 2007
  • Publish Date: 25 Dec 2007
  • To investigate the characteristics of coupled vibration of bridge deck and cable of a long-span cable-stayed bridge,a model for the coupled vibration of bridge deck and cable was established,and then,the effects of the frequency ratio of bridge deck to cable,the inclined angle of cable and the mass ratio of bridge deck to cable were respectively analyzed by numerical simulation.The research results show that the resonance occurs not only when the frequency ratio is 1,but also when it is 1/2 and 2.With the increases of the inclined angle and the mass ratio,the resonance amplitude will decrease when the frequency ratio is 1,but it will increase obviously when the frequency ratio is 1/2 and 2.
