Abstract

The mechanical behavior of steel fiber reinforced concrete (SFRC) is strongly dependent on the cracks bridging brought by fibers. Thus, the fibers orientation in SFRC is one key factor. This research extends a micromechanics-based model to describe the shear transfer in addition to tensile mechanisms at the crack surface and to establish a base at micro-scale for the further homogenization at the macro-scale. The shear effect is described as a function of the fiber pullout process, the stress across the cracks is then derived from the integration of the product of the fiber pullout function by the probability of the fiber location and orientation. The simulation results provide the SFRC behavior under mixed-mode displacement of crack (slip and opening). The influence of material parameters is investigated.
