## Abstract The cables in a cableโstayed bridge usually possess low inherent damping and are prone to windโinduced, trafficโinduced, and windโrainโinduced vibrations. This paper establishes an active control algorithm using the stiffness control method to suppress windโrainโinduced vibration of pro
The paper addresses an active control of the resonant vibrations of composite beams performed by a parametric stiffness modulation. A sandwich beam composition with the continuous core is considered. The stiffness modulation is introduced by some fairly small changes in an orientation of elements of
Viscous dampers have been widely used for mitigating rain-wind-induced vibration of bridge stay cables. Designing a damper with optimal damping in a specific mode may leave the cable susceptible to vibration in other modes, and it is almost impossible to specify a priori the dominant mode in which o
