In the fabrication process, a number of parameters influence the distribution and orientation of fibers within individual structures. This phenomenon leads to a large scattering of flexural responses in SFRC beams. Consequently, prediction models of the flexural behavior of SFRC beams that do not consider the variability of fiber distribution often overestimate or underestimate the response. This paper presents a novel approach for estimating the flexural behavior of SFRC beams using X-ray photograms to account for the variability of the fibers.
