This work evaluates the influence of steel fibers on the bond between reinforcement and concrete and the behavior of beams subjected to bending stress in the Ultimate Limit State, through an innovative test to compare with RILEM RC6 (1983) standard test. Some of the theoretical models that are willing to represent the bond behavior are prescribed by CEB-FIP (2010), ACI 408R (2003) and NBR 6118 (2014) and by the authors' proposed models: Orangun et al. (1977), Harajli (2009), Shen et al. (2016). In the experimental program will be analyzed steel bars with diameters of 8 mm, 10 mm and 12.5 mm in specimens molded with compressive strength concrete of 30 MPa, varying the length of development in lb; 0.75.lb and 0.5 lb (lb is anchorage length...
