Abstract
Abstract
Shear strength of fiber reinforced concrete (FRC) has its prime importance in structural design. Concrete members like brackets, corbels and ledger beams may fail in direct shear. Such failure can be sudden and brittle. The presences of fibers positively affect the behavior of concrete, as it increases the residual shear transfer and reduces the formation and extension of cracks. As many parameters affect it, shear strength of FRC is precisely detected. Experimental investigation was carried out to study the shear transfer of un-cracked fibrous concrete. This study investigates the behavior of shear strength of FRC beams and the direct shear strength of FRC by testing push-off specimens. The experimental parameters were the type of fibers, the volume percentage of fibers, the concrete compressive strength and the presence of stirrups in beams. Test results showed that presence of fibers increases the concrete shear strength, reduces numbers and width of cracks and increases the stiffness and ductility. The use of steel fiber experienced more shear strength, ductility and stiffness than glass fiber.
