Mechanical properties of concrete and mortar reinforced with randomly distributed smooth steel fibers were investigated to study the mechanism of fiber reinforcing. It was observed that the significant reinforcing effect of fibers is derived after the cracks are initiated in the matrix, similar to the conventional tensile and stirrup reinforcement. The postcracking resistance of fibers was considerably influenced by their lengths, orientation and stress- strain relationship. The spacing of reinforcement appears to have little influence on crack propagation.
