FULL-SCALE MEASUREMENTS OF TOWERS AND MASTS AND COMPARISON WITH THEORETICAL SIMPLIFIED ANALYSIS

摘要

The wind action and response of towers and masts to turbulent wind are described in the paper. The results of full-scale measurements carried out on one tower and one guyed mast are presented. The measured characteristics, especially the power spectral densities of the wind velocities and the structure response, are compared with theoretical presumptions. The measured structures are situated in different terrains. Subsequently, a practical method for the theoretical evaluation of the structure response to turbulent wind is proposed. The method, based on the spectral analysis approach, takes into account the contribution of all significant mode shapes. The method can be used for a wide range of towers and masts, especially for those which do not meet EN standards criteria for commonly used equivalent static methods.
