The tensile response of ultra-high performance fiber reinforced concrete (UHPFRC) is a fundamental material property and its engagement in the design of structural components requires a throughout understating of the different factors affecting it. In particular, the tensile cracking strength is one of the main parameters adopted for the idealization of the tensile constitutive law. However, the tensile response of UHPFRC is not an intrinsic property as it depends on several factors including the material formulation, the geometry of the components, the casting process, and the testing method and specimen. In this paper, the effect of the fiber reinforcement on the tensile cracking strength is discussed through the analysis of experimental results reported in plain UHPC and UHPFRC with different preferential fiber alignments.
