Abstract:	Der rechnerische Querkraftnachweis von Stahlbetontragwerken ohne Schubbewehrung (im Allgemeinen Platten, bspw. Fahrbahnplatten, WEA-Fundamente) auf Ermüdung nach DIN EN 1992-1-1 [1] bzw. DIN EN 1992-2/NA beruht weitgehend auf empirischen Untersuchungen. Der Ansatz wurde bislang kaum experimentell validiert. Nachfolgend wird über theoretische, experimentelle und numerische Untersuchungen zum Tragverhalten von Stahlbetonbalken ohne Querkraftbewehrung unter dynamischen und statischen Einwirkungen berichtet. Neben der Validierung des Normansatzes mittels 20 Balkenversuchen konnten auch die Tragmechanismen nach Auftreten eines Biegeschubrisses studiert werden. Fatigue strength of RC beams without transverse reinforcement under cyclic loads The shear design of RC members without transverse reinforcement (e.g. slabs, bridge decks, footings of wind energy plants) for fatigue loads is based on empirical approaches, which had been rarely validated by experiments. This paper presents theoretical, experimental and numerical studies, which aim to give a better understanding of the load transfer in RC members without web reinforcement under static as well as cyclic loads. Furthermore, the approach of Eurocode 2 will be examined.
