The segment construction method for wind turbine towers has established itself in the production of large hub heights in the form of hybrid constructions. Hybrid towers consist of steel pipes in the upper part and usually pre-stressed reinforced concrete segments in the lower part. The horizontal joints in the reinforced concrete structure are generally constructed as a grinded dry joint without shear serrations. Therefore, shear forces in the joints can only be transmitted by friction, especially for the calculation of the ultimate limit state (ULS), in which case torsion is relevant and the joints open due to a bending load. The current theories are based on the known torsion theories according to Saint-Venant, which are not fully applicable to this construction method. Based on the theoretical considerations from [1], a torsion support model for circular ring segments with dry joints is developed in this paper. Subsequently, this model is compared with numerical simulations and experimental results.
