Abstract: The present invention relates to a support structure for wind-driven power generators comprising a tubular tower (1) with multiple superposed, post-tensioned annular sections (20) from the crown to the foundation, each being formed by at least two pieces of prefabricated concrete wall (10) defining between them vertical joints (12), each wall piece (10) having two transverse joint faces (13) and two vertical joint faces (14); wherein in the vertical joints (12), the vertical joint faces are arranged facing one another and lack structural connectors between them for the transmission of structural stresses, allowing for an independent structural behavior of the mentioned wall pieces (10), the height of the wall pieces (10) being less than twice their width.

Abstract: 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.
