This chapter first introduces fundamentals of cable dynamics in order to lay down a foundation for better understanding of wind‐induced vibration and rain‐wind‐induced vibration (RWIV) of stay cables. Wind‐induced vibration of stay cables mainly refers to buffeting by wind turbulence, vortex‐induced vibration, galloping of dry inclined cables and wake galloping for groups of cables. A possible mechanism of RWIV is then discussed and a simple analytical model is presented. This model, together with the fundamentals of cable dynamics, is applied to predict the RWIV of full‐scale stay cables. To foresee whether RWIV will occur for a particular cable‐stayed bridge at a particular bridge site, a framework for predicting the probability of its occurrence is finally presented.
