Abstract:	Die Grundidee der Stahl-UHFB - Stahlbeton Verbundbauweise besteht darin, mit einer UHFB-Schicht, die in Haupttragrichtung mit Bewehrungsstäben versehen ist, Bauteile aus herkömmlichem Stahlbeton zu verstärken, indem deren Tragfähigkeit erhöht und die Dauerhaftigkeit verbessert werden. Dadurch können die bekannten Schwachstellen und Mängel der Betonbauweise eliminiert werden. Es wird ein Überblick über die Stahl-UHFB - Stahlbeton Verbundbauweise gegeben, indem die wesentlichen theoretischen Aspekte des Tragverhaltens von Stahl-UHFB - Stahlbeton Verbundbauteilen kurz erläutert und anhand von Anwendungen bei der Instandsetzung und Verstärkung bestehender Betonbauten illustriert werden. Schließlich werden Möglichkeiten des Einsatzes dieser neuartigen Bauweise beim Bau von neuen Tragwerken aufgezeigt. Strengthening of existing reinforced concrete elements using Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) An original concept is presented for the strengthening of concrete structures. The main idea is to use Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) complemented with steel reinforcing bars to strengthen those zones of the structure that are exposed to severe environmental influences and high mechanical loading. This concept combines efficiently protection and resistance properties of UHPFRC and significantly improves the structural performance of the rehabilitated concrete structure in terms of durability. Properties of UHPFRC are outlined and the essential theoretical background of structural behavior of R-UHPFRC - RC composite elements is given. This novel technology has been validated by means of field applications.
