Stay cables are an important part of cable-stayed bridges, with characteristics of its low quality, stiffness and damping, among which rain-wind-induced vibration brings the most serious damage in its high amplitude because of its easy conditions to meet. Based on the wind-rain-induced vibration theory of cable-stayed bridges, this paper introduces the wind-induced vibration and control measures of cable-stayed bridges, and the research methods of cable-stayed wind-rain-induced vibration. The results show that: Only when the upper waterline is at a position angle of 40°~70°, the aerodynamic coefficient changes significantly, and galloping may occur. From the perspective of wind resistance, a stay cable with a larger spiral parameter K1 and K2 between 0.01 and 0.03 should be selected according to the actual situation.
