| Abstract: | The wind-induced vibration response of geodesic single-layer spheical reticulated Shells is analyzed in frequency domain method in this paper during usual varialable range of seven kinds of basic parameters .And the influence of all kinds of parameters on wind-induced vibration response and wind-induced vibration coefficient of controlling response.Then by statistically analyzing and summarizing results, of which on the basic generalization is dealed with from theory, at last practical wind-resistant design method of geodesic single-layer spherical reticulated shells is proposed. |
