In this paper the conception of initial equilibrium state is introduced to analyze the strained condition of guyed transmission tower for the first time. Principle of finite-element method is applied to deduce the stiffness matrix which is based on UL (Update Lagrange Description) method with the consideration of bi-nonlinearity, also, the stiffness matrix of beam element with one rigid joint and one hinged joint is worked out. Taking a guyed transmission tower as an example, cable-beam assembly nonlinear finite element model is built by using general finite analytic software ANSYS. On these bases, the initial prestress of guyed transmission tower under initial equilibrium state is figured out. At last, the result of numerical analysis is proved by model test.
