Abstract: Highly relevant and promising research has been carried out in the domain of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) during the last two decades. However, except for some pilot projects e.g. Gärtnerplatz Bridge, UHPFRC has not yet arrived in Germany’s construction practice. In order to push forward this efficient technology and bring it to practice, two R&D projects have been launched in cooperation with several industrial partners. The main focus is to develop structures that use the high performance of UHPFRC efficiently while also enabling simple design and production.
In this paper the general approach of the ongoing R&D projects is explained. The conceptual design of the structures, the detailing concept of the shear joint is discussed. Moreover, the bending behaviour of the precast girders as well as an economic evaluation of the developed UHPFRC structures is presented.
