Abstract：Based on the multi-degree-freedom model, simple models of two typical 500kV transmission towers are established. The wind-induced responses of simple models of transmission towers are computed according to wind tunnel test, and compared with the results by the finite element models. Moreover, calculating error and applicability of simple model are analyzed. The studies show that simple models are not applicable to calculating the local responses of truss members, but have high accuracy and efficiency for the whole characteristic responses of overall structure.
