Concrete beam minimum shear reinforcement
WebMar 1, 2003 · Date: 3/1/2003. Abstract: A theory for the shear strength of reinforced concrete ordinary (slender) beams subject to shear and flexure is described. According to the theory, the reason for shear failure is the loss of the shear force of the steel bars of main tension reinforcement, which occurs due to a horizontal splitting of concrete cover ...
