Wind and Rain Vibration Excitation Model of Cables Considering the In-plane and Outer-plane Vibration

On the basis of summarizing the characteristics of rain-wind-induced vibration of stayed cables, the wind-induced vibration force of in-plane and outer-plane is studied, and the motion equation of cables when free vibrated and when wind-induced vibration and damper interacted. With the Galerkin multimodal truncation method, the two expressions of the motion equations of the continuous system are studied, and their correlations are discussed. On the basis of discretization, the possibility of numerical calculation is considered. The solution strategy of the continuous system is presented when dampers are added.
