Abstract: This paper describes the results of an experimental test program carried out to study the correlation between the tensile properties of a UHPFRC material and the flexural response of structural panels. The material tensile response was characterized through a direct tension test method using both mould cast and extracted specimens and validated through an image analysis technique. A significant effect of the casting process on the fiber orientation distribution and thus on the material tensile properties was observed and quantified at different specimen orientations. In order to correlate the material tensile properties and the flexural response of structural components, one-way and two-way flexural tests on UHPFRC panels were also completed and analyzed in light of the previous material characterization results. The fiber orientation distribution derived from the casting process and the element configuration were key factors in the structural response of the UHPFRC panels, particularly for elements tested in the one-way configuration with no structural redundancy. A good agreement was observed between the experimental results and the response estimated through a sectional analysis.
