Method of design and manufacturing concrete structures subjected to relevant cyclic loads along their service lives, as wind towers, and a fatigue testing machine. The method consists on the design of concrete structures conditioned by cyclic loads considering a fatigue strength value specified by the project as one of the main design parameters, which will be verified during the manufacturing phase as one of the control parameters of the quality assurance plan by performing fatigue strength test on concrete samples representative of the concrete structural elements produced on said manufacturing phase. The method allows to decouple the concrete fatigue strength from the compressive strength of the material, which is why includes a verification of the fatigue strength as a part of a quality assurance plan of production according to a new developed procedure.

The invention relates to a method and tooling for manufacturing prestressed concrete members by molding, including the assembly of a rebar cage (20) outside a mold (10), with the inclusion of prestressing tendons (30) fixed in a position coinciding with, or proximal to the final position thereof with respect to the rebar cage (20). The rebar cage (20), together with the tendons, is introduced into a mold, the tendons extending along the length of the mold, with two gripping portions (31) for each tendon projecting from the mold (10) through two facing opposing faces (11) of the mold (10). The gripping portions are then introduced into elongate openings defined by separation gaps existing between parallel and opposing walls (42) forming part of at least two prestressing masts (40). Subsequently, the tendons are tensioned, and the concrete member to be manufactured undergoes concreting and setting.
