Based on the updated Total Lagrangian Formulation, the large deflection stiffness matrices of space member and guy elements are derived in this paper. A mass matrix of guy clement is deduced according to the principle of virtual work, and the nonlinear static and dynamic incremental equilibrium equation of guyed towers is established. The Newton-Raphson and modified are-length iterative methods are adopted to solve the whole deflecting procedures of guyed tower before and after instability. The sub-space iterative method is used find arbitrary numbers of lower modes and periods of vibration of guyed towers, and the incremental Wilson-θ method is used to solve the dynamic responses of guyed towers under arbitrary input earthquake waves. Numerical examples show that the analytical method of this paper is accurate and efficient for nonlinear stability and vibration analyses of guyed towers.
