An overview of the flexural post-cracking behavior of steel fiber reinforced concrete
This paper provides a general overview of recent developments in the study of the flexural post-cracking behavior of steel fiber reinforced concrete (SFRC). The results of three-point-bending tests (3PBTs) performed at the University of Brescia during the last lustrum were collected in a broad database consisting of 81 series for a total amount of 528 beams. Several experimental parameters were investigated: strength of concrete matrix, fiber dosage, fiber aspect ratio, fiber filament tensile strength, as well as fiber orientation. The latter was deeply studied by means of image analysis of cut cross sections. The results, discussed in terms of post-cracking flexural residual strengths, highlight that all the parameters studied contribute to the post-cracking performances exhibited by SFRCs
