Title:	Torsionstragverhalten von Betonhohlquerschnitten in geschlossenen und klaffenden Segmentfugen - Teil 3: Verifikation des Berechnungsmodells
Abstract:	Betonfertigteile für segmentierte Türme von Windenergieanlagen sind Serienprodukte, die im Sinne der Nachhaltigkeit möglichst ressourcenschonend zu bemessen sind. Dabei sind die Querkraft- und Torsionstragfähigkeit der Fugen in der Bemessung der Betonfertigteiltürme von großer Bedeutung. In den Teilen 1 und 2 dieser Veröffentlichungsreihe wurde ein neues Berechnungsmodell für die Fugentragfähigkeit vorgestellt, welches im vorliegenden 3. Teil anhand von Versuchsergebnissen und FE-Berechnungen verifiziert wird. Zusätzlich wird ein Vergleich zu anderen Modellen gezogen und die Anwendungsbereiche der Modelle werden eingegrenzt. Torsional structural behavior of hollow concrete cross-sections in closed and gaping segment joints - Part 3: Verification Precast concrete elements for segmented towers of wind turbines are series products that must be designed to be as resource-efficient as possible in terms of sustainability. In this context, the shear force and torsion load-bearing capacity of the joints are of great importance in the design of the precast concrete towers. In parts 1 and 2 of this publication series, a new calculation model for the joint load-bearing capacity was presented, which is verified in the present 3rd part on the basis of test results and FE calculations. In addition, a comparison to other models is made and the application areas of the models are narrowed down.
