Abstract :
Stay cable is one of the main components of cable stayed bridge to bear loads. Due to its large flexibility, small quality and small damping, various of harmful vibrations could happen easily under the external excitations. Rain-wind-induced vibration is the strongest form of vibrations. Through the establishment of Dof theoretical model of rain-wind-induced vibration and the analysis of vibration frequency and aerodynamic damping of cable, the occurrence mechanism of rain-wind-induced vibration is revealed. The vibration control measures for this kind of vibration are also established to support the ensurance of bridge operation.
