Abstract The geometries of metallic tubular towers directly influence the interaction between wind action and the structural response of the tower itself. Analyzing these configurations and understanding how this interaction occurs is fundamental for proper structural design. The developed investigation presents and discusses the results obtained from a parametric study of wind influence on a metallic tubular tower with different geometries, taking into account second‐order effects according to Eurocodes 1 and 3. The goal is to observe and analyze the influence of the variation of key tower parameters on its structural response, as well as the impact of these variations on the wind–structure interaction. For this purpose, different geometric configurations were considered, varying the number of sides of the shaft and the base and top diameters of the tower, while maintaining a constant wall thickness for the shaft. The global behavior of the structure was analyzed, focusing on obtaining key tower parameters such as top displacement, maximum deformation, maximum stress ratio, and structural weight. Wind‐induced loads and the influence of geometric variations were also analyzed to determine parameters related to wind–structure interaction, such as the structural coefficient (cscd), which accounts for the non‐simultaneity of peak pressures on the surface together with the effects of vibrations caused by turbulence. The results make it possible to identify relevant trends and sensitivities for the efficient design of metallic tubular towers subjected to wind action, contributing to the development of more optimized design guidelines.
