Abstract: Local parametric vibrations of stay cables in Megami steel cable-stayed bridge are studied in the present paper. Natural frequencies of the global modes are obtained by using the three dimensional FEM model and the natural frequencies of the stay cables are obtained by analytical solution. The effect of the cable vibration on the global vibration are evaluated at first. The global motions under the sinusoidally time-varying excitation using the exciter are evaluated by using the method of modal analysis. The local parametric vibrations of the stay cables, which are subjected to time-varying displacement at a support during global motions are obtained and the properties of the local vibrations are discussed.
