Maximum displacements Specific control points were defined on each structure: - Points A were placed at the top of each structure, precisely at the nodes exhibiting maximum displacements. - Points B were added only for towers where maximum displacements were considered worrisome at 8 m in height, where a reduction in thickness is observed. This was the case for all the structures under study. Tab. 10 summarizes the coordinates of the control points A and B that were selected on the six structures under study, and the figs.39-44 show the positions of the displacement control points relative to the selected axes.
