Abstract: A semi-finished part for a foundation of a tower construction, in particular of a wind turbine tower, comprising at least two semi-finished part foundation segments, which each have an outer delimitation element and a reinforcement, which is connected to the outer delimitation element and comprises struts protruding from the outer delimitation element, wherein: the outer delimitation elements of the semi-finished part foundation segments form an outer edge, which delimits an interior to be later filled curable casting material; and the reinforcements of the semi-finished part foundation segments extend from the outer edge into the interior.

Abstract: A manufacturing method for producing a tower segment, a tower portion and a tower section for a tower, in particular for a tower of a wind power installation. A tower segment, a tower portion and a tower section for a tower, in particular for a tower of a wind power installation, to a tower, and to a wind power installation.

Abstract: A method for establishing operating loads, in particular wind loads, for tower structures, in particular for tower structures for wind power installations is provided. Provided is a method for designing a tower structure, in particular a tower structure for a wind power installation, a method for determining the service life of a tower structure, in particular a tower structure for a wind power installation, and a tower structure, in particular a tower structure for a wind power installation, and a wind power installation. The method for establishing operating loads for tower structures comprises establishing a load parameter in a load direction, establishing a load direction occurrence distribution, establishing a load parameter modified by the load direction distribution.
