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

Wu, Liang  ,  Zuo, Delong

Description
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.
