Abstract: 
Ultra-high performance fibre reinforced concrete (UHPFRC) has an important potential to allow innovative design due to its high mechanical properties and its durability. This paper reports some results of a theoretical and experimental research carried out at the University of Applied Sciences (UAS) Fribourg/CH, on UHPFRC structural elements. The experimental studies included load tests on beams, slab stripes and slabs. In a first study, consisting of 25 beams, the behaviour of linear elements subjected to bending and shear stresses was analysed. A second study dealt with the behaviour of 38 thin slabs strips in uniaxial bending. The third study was dedicated to the behaviour of 22 thin slabs subjected to concentrated loading. Finally, in a fourth study, the behaviour of 16 thin slabs exposed to biaxial bending stresses was analysed. The results of these studies contribute to the development of a recommendation of the Swiss Society of Engineers and Architects (SIA) for the design and the construction of UHPFRC structures.
