Abstract: It comprises providing at least two metal shell segments arranged adjacent to each other, forming a column of concrete on at least a joint portion of adjacent shell segments, placing a formwork to form said column of concrete, assembling a support framework before providing shell segments, providing an auxiliary sub-structure internal to the shell segments, and an attaching formwork associated both with the internal support framework and to the shell segments. The assembling of the internal support framework may be carried out by providing at least a first series of auxiliary pillars, joining the auxiliary pillars to each other to form a first auxiliary sub-structure and arranging an attaching formwork attached to said auxiliary pillars.

Abstract: A tower section for a wind turbine tower structure comprises at least two shell segments defining, in an assembled condition, a substantially hollow structure, and including first connecting means for mutually joining two adjacent shell segments along a joint, which comprise a column of concrete arranged overlapping at least part of the joint between adjacent shell segments. A method for building a tower section for a wind turbine tower structure and a wind turbine comprising a nacelle having rotatable blades and a vertical tower made of at least one of such tower sections are further provided.
