The nonlinear vibration of the cable-stayed beam under two-to-one internal resonance is investigated.Considering the continuity conditions, the extended Hamilton principle is applied to derive the 3D nonlinear motion equations of the cable-stayed beam.Then the multimodal discretigation and the method of multiple scales are used to obtain the modulation equations.
