Considering the dynamic interaction between the mast and guys, the coupled dynamic equations of guyed mast structures are derived. The paper discussed how the spatially correlated wind velocity is generated form filtered white noise. Then, based on the idea of the discrete analysis method of random vibration and Gaussian closure theory, the paper studied the wind-induced responses of guyed masts when taking into account the non-linearity of guys. The nonlinear discrete random vibration method can calculate accurate mean and mean square responses, the wind responses analysis for a numerical example and a wind tunnel experiment model demonstrated this point. In addition, the linear discrete random vibration method can be used for weakly nonlinear structures, which is favor of the consumed computational time.
