Abstract:Paper presents extensive data on the influence of steel fibers, alone or in conjunction with conventional stirrups, on shear transfer in concrete. The test specimens used in this study were of the push-off type with an initially uncracked or cracked shear plane. The main variables investigated include fiber volume, amount of stirrups, and the type of concrete. The results show that fibers enhance the ultimate shear transfer strength in both uncracked and precracked specimens. In the latter, the ultimate shear strength can be expressed on the basis of Coulomb's criterion. Fibers increase the residual shear transfer strength, and the shear transfer stiffness can be related to crack width. The shear transfer strength was generally lower in lightweight concrete than in normal-weight concrete.
