An experimental investigation was carried out to study the shear behavior of steel fiber reinforced concrete beams with rectangular section, the major parameters were the distance between stirrups and the volume ratio of steel fiber. Based on the analysis of the test results, the theoritical model and the practical formula for calculating the shear-crack width of steel fiber reinforecd concrete beams are proposed.
Keywords: steel fiber reinforced concrete; beam; shear-crack width
