Abstract
The dynamic behaviour of guyed masts depends on the dynamic behaviour of the guys. The dynamic behaviour of guys under wind load is studied. The main excitation is the mast shaft movement, which moves the upper guy connection points. Due to the nonlinear behaviour of the guys the dynamic amplitudes are reduced. In a linearized calculation this effect can be taken into account by using an equivalent damping. Near the resonance chaotic motions occur. The additional influence of gusty wind which hits the guys directly is investigated. It is shown that the influence on the overall behaviour of a guyed mast is negligible. Comparisons of theoretical and experimental results show that a precise prediction of the dynamic response of guyed systems is possible if the dynamic behaviour of the guys is taken into account.
