“…Several relevant mathematical models that have been developed produce results that correlate and converge with some series of experimental data [13,14], while, in other cases, they exhibit significant divergence [15]. Such models examine the operation of fibers and their effectiveness not only in crack control, but also in the improvement of the mechanical characteristics of concrete (direct tensile strength and compressive strength within a biaxial or triaxial stress field) and the interrelation of various factors.…”

Abstract:The tensile behavior of concrete or mortar plays an important role for delaying the formation and propagation of cracks, and also for upgrading the bearing capacity of existing concrete and masonry constructions. Although the presence of steel fibers is known to improve, often considerably, the tensile capacity of concrete members, methods for the quantification of this improvement are still limited. For this reason, a model has been developed for the prediction of the tensile strength of steel fiber-reinforced concrete members, as crack opening occurs. Given the geometry and the physical characteristics of reinforced concrete member and fibers, the model predicts: (1) the number of fibers crossing a crack's surface; (2) the distribution of these fibers in terms of (i) the angle a fiber forms with the crack surface (fiber inclination) and (ii) the embedded length of the fiber at both sides of the surface; (3) resistance to crack opening provided by each fiber, in relation to its position and inclination. On the results of the results obtained, the influence of the number of fibers on the reduction of crack widening in concrete or mortar is remarkable and can be estimated with satisfactory precision. In upgrading existing concrete and masonry constructions, this tensile behavior is found to play important role.

“…However, studies by Dupont and Vandewalle (2005) and Lee and Kim (2010) show that in normal usage conditions, or rather, without the damaging interference of fiber disposition, FD≈0.5, as a rule. Further, a significant number of fibers parallel to the prisms´ Latin American Journal of Solids and Structures, 2018, 15(7), e86 8/16…”

The efficiency of steel fibers for shear strength of reinforced concrete beams is assessed. Four beams were evaluated: control consisted of one beam without any steel fibers and three beams with reinforced concrete with steel fibers. All beams were reinforced for shear strength by a minimum reinforcement rate. The influence of fiber content added to concrete, at 0.5%, 0.8% and 1.0%, and the possibility of partial or total replacement of conventional shear reinforcement (stirrups) by steel fibers were evaluated. Results showed a significant increase in ductility and stiffness of the beams with steel fibers and, consequently, changes in the failure mode were observed, of shear (control beam) to flexure behavior (beams with steel fibers).
