Abrégé
In a first embodiment, the present invention comprises a thin-wall monotubular tower with a metal column of varied cross sections in the form of a truncated cone, formed from the connection of modules M1 to Mn; in which the ratio of the diameter (D) to the thickness (t) of each column module is between 75 and 250; and in which at least one module of the tower has a varied frustoconical cross section with a taper between 1:50 and 1:90. In a second embodiment, the present invention comprises a thin-wall triangular tower with three thin-wall metal columns arranged in triangular fashion; in which the thin-wall columns have a diameter/thickness (D/t) ratio of 25 to 115; and in which at least one module of the tower comprises at least three columns, the cross section of each column whereof is frustoconical with a taper between 1:125 and 1:395.

Abrégé
The invention relates to vertical structures designed to bear high loads, more particularly lattice towers used for wind turbines and other uses, and characterised in that it comprises three metallic columns arranged in a triangle about a vertical axis of the lattice tower, each metallic column having a cross-section with a closed profile, the distance between the centres of the metallic columns being greater than 4 metres in the region of the tower base, an angle of inclination of the central longitudinal axis of each metallic column in relation to the vertical axis of the tower ranging from -1.7 to +1.7 degrees, and the height of the lattice tower being greater than 60 metres, and in that it comprises a plurality of wind bracing and auxiliary wind bracing members, as well as a support platform arranged in a region of the top of the tower.
