Abstract
The cables in a cable‐stayed bridge usually possess low inherent damping and are prone to wind‐induced, traffic‐induced, and wind‐rain‐induced vibrations. This paper establishes an active control algorithm using the stiffness control method to suppress wind‐rain‐induced vibration of prototype stay cables. By neglecting the axial inertia force and the modal coupling, the governing equations of motion of wind‐rain‐induced vibration control of prototype stay cables with active stiffness control algorithm are first derived. The fourth‐order Runge–Kutta method is then introduced to find the numerical solutions to the problem. Extensive parameter studies have been carried out for investigating the features of the control method as a design guideline. Copyright © 2007 John Wiley & Sons, Ltd.
