In this paper, nonlinear implicit finite element analyses are used to explore parametric excitation of a bridge stay cable resulting from cyclic motion of the deck. "Parametric excitation" is excitation of a cable mode with deck motion at near twice the frequency of the excited mode. Third-mode parametric frequency response curves are consistently predicted when the finite element mesh is sufficiently small. With low damping, large-amplitude parametric response develops quickly. Reaction moments at the deck and tower increase by a factor of two when large-amplitude motion ensues from parametric excitation.
