Abstract: 
AFGC SETRA Interim recommendations have proposed in 2002 a way to assess fibre orientation factor in UHPFRC structural members. The method has been then used on most of the major structural UHPFRC projects in France and the aim of this contribution is to present a ten year feedback of it. In a first part, the method principle will be presented extensively through a classical bridge project: Pont de Saint Pierre La Cour. In a second part, key results obtained with projects such Achères shells, Bourg-les-Valence bridge, Pinel bridge and “Pont du Diable footbridge” will be compared and analysed with respect of casting methods employed. In sum, this practical K factor method has shown robustness and reliability that no other non-destructive method has proposed from now.
