Conference Paper Analytical and numerical evaluation of coupled galloping of slender towers

Wu, Liang  ,  Zuo, Delong

Many previous studies have been conducted to study galloping of slender structures or structural components. While some recent studies have investigated the problem of coupled galloping involving the across-wind and along-wind vibrations, few of these investigations focused on the prediction of the steady-state amplitudes of coupled galloping oscillations. This paper presents a state-space formulation of the equations of motion for the analysis of coupled translational galloping of full-scale structures under the quasi-steady assumption. A numerical procedure based on the Fourth-order Runge-Kutta method is used to solve these equations of motion and predict coupled galloping amplitudes. A full-scale tower which has been observed to exhibit coupled galloping is used as an example structure to illustrate the application of the proposed analytical-numerical formulation.
