The paper presents results of an experimental study that analyzes the shear behavior of steel fiber-reinforced concrete. Direct shear push-off tests are carried out on normal- and high-strength steel fiber-reinforced concrete specimens. The test can be performed in a stable manner for steel fiber-reinforced concrete, permitting the determination of the pre- and post-peak responses and, consequently, characterizing the shear stress that can be transferred across an open crack. The shear stress-slip response is analyzed and toughness-based parameters, for possible use in design, are calculated.
