In cables, near resonance time-varying loading causes large amplitude oscillations involving mainly the resonant mode. The contribution of higher modes may arise due to either internal coupling phenomena or peculiar spatial distribution of the loading. Using analytical reduced models and finite element models, the paper explores the relevance of the modal interactions in both planar and spatial response to harmonical in-plane excitation and to out-of-plane wind turbulence with its spatial distribution.

Abstract
In cables, near resonance time-varying loading causes large amplitude oscillations involving mainly the resonant mode. The contribution of higher modes may arise due to either internal coupling phenomena or peculiar spatial distribution of the loading. Using analytical reduced models and finite element models, the paper explores the relevance of the modal interactions in both planar and spatial response to harmonical in-plane excitation and to out-of-plane wind turbulence with its spatial distribution.File in questo prodotto:
