Abstract
An experimental investigation into the structural behavior of brackets with plain and fibrous concrete and in the presence of steel bars is addressed in this research. Both brackets have the same shape and dimensions. Testing of nine steel fibrous reinforcement concrete specimens and one reinforced concrete with compressive strength (28.6) MPa under vertical repeated load. The test results in terms of load versus deflection curves, stiffness, ductility and crack patterns show the effectiveness of using steel fibrous concrete to ensure a superior strength and deformation capacity in reinforced concrete bracket. Test results showed that, addition of steel fibers (1.5) % by volume of concrete and horizontal stirrups improve both shear strength and ductility of the tested brackets, and results in a more ductile failure mode.
