This paper presents an overview of existing theoretical methods for the analysis of motion-induced and parametric excitations of stay-cables. Application of the methods is illustrated with a practical example of assessment of stay vibrations due to wind buffeting on the proposed Ironton-Russell Bridge, in Ohio. The results obtained from this analysis are compared against direct numerical (finite element) simulations. The selected scheme for cable vibration mitigation is presented, together with a discussion of its effectiveness.
