The research and the use of fiber reinforced concre te (FRC) are widely diffused throughout the world. However, in Brazil there are no normativ e prescriptions that establish parameters for the use of FRC. Thus, the present wo rk aims to evaluate the mechanical behavior of concrete samples reinforced with steel fibers (SFRC) by means of the simplified Barcelona test, since this test is simpl er than those frequently used. For the accomplishment of the Barcelona simplified test (BS T) cylindrical test specimens with 15 cm of diameter and 15 cm of height were tested. The experimental program consisted in evaluating composites with two compressive strength s (20 MPa and 40 MPa) and three dosages of fibers (40 kg/m3, 50 kg/m3 and 60 kg/m3) . 72 cylindrical specimens were molded for BST, and this study integrated an interl aboratory program between the Faculty of Civil Engineering of the Federal University of U berlândia and the Polytechnic School of the University of São Paulo, in order to analyze an d compare the results found in both laboratories. All specimens were assayed at age clo se t 240 days. After analyzing the obtained results, it was possible to conclude that t e simplified Barcelona test shows signs of repeatability and reproducibility. It has also b een found that the addition of steel fibers to the concrete gives the same benefits in terms of modulus of elasticity, compressive strength, diametral compression tensile strength an d, in particular, toughness.
