Title:	Verbindungen von Fertigteilen aus UHPC
Abstract:	Bauteile aus ultrahochfestem Beton (UHPC) werden insbesondere in Fertigteilwerken hergestellt. Daher sind tragfähige und wirtschaftliche Verbindungen von UHPC-Fertigteilen von besonderer Bedeutung. In Verbindungen von Bauteilen können Schub-, Druck- oder Zugkräfte oder Kombinationen aus diesen Belastungen auftreten. In dem vorliegenden Beitrag werden die im Rahmen des Schwerpunktprogramms 1182 “Nachhaltiges Bauen mit ultrahochfestem Beton” der Deutschen Forschungsgemeinschaft (DFG) durchgeführten Versuche zur Ermittlung der Tragfähigkeit wesentlicher Knotenpunkte von Fertigteilen beschrieben und die Ergebnisse diskutiert. Die Versuchsergebnisse dienen der Entwicklung von Ingenieurmodellen zur Bemessung von Fertigteilverbindungen aus UHPC. Connections of precast UHPC elements Ultra-High Performance Concrete (UHPC) elements are particularly suited for precast construction. To utilise the high structural performance of single UHPC elements, solid and economical connections are essential. Such joints are exposed to shear, compressive or tensile forces or combinations of these. This paper presents tests on the load bearing capacity of UHPC nodes. All tests have been carried out within the priority programme 1182 “Sustainable Construction with UHPC” of the German Research Foundation (DFG). The test results provide a basis for construction recommendations of connections for precast UHPC elements.
