Shear Behavior Of Reinforced High-Strength Concrete Beams Without Shear Reinforcement
MetadataShow full item record
Eighteen rectangular singly reinforced high-strength concrete beams without web reinforcement were tested in combined shear and flexure. The main variables were the longitudinal steel reinforcement ratio and the shear-span to effective depth ratio. The uniaxial compressive strength of concrete was about 93 MPa (13,500 psi). The experimental shear capacities were compared with the shear capacities predicted by different empirical equations presented in literatures. Two empirical equations have been proposed to better predict the shear capacity of reinforced high-strength concrete beams without stirrups.
