In this paper, a study is conducted on the relationship between fibre orientation and fibre volume fraction and residual flexural tensile strength. In order to do this, one steel fibre reinforced concrete deep beam was casted. A set of prismatic specimens were extracted from different parts of this deep beam and with different orientations. First, all these specimens were subjected to a computed tomography (CT-Scan) study in which the fibre orientation and fibre volume fraction was determined. These specimens were then subjected to 3-point bending testing, in accordance with current standards, and the residual flexural tensile strengths values were obtained (fR,i).
