(57) 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 alements 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.
