Design of SFRC Members for Shear
Abstract The inclusion of steel fibers in the concrete leads to improvement of strength properties of concrete, with an enhanced post-cracking tensile resistance and the toughness. The fibers present in the concrete transfer the tensile stresses across the cracks formed in a flexural member once the strain caused by external loading exceeds the limiting cracking strain of the material and significantly delay the crack widening and their subsequent propagation in the member. The reduced crack widths and improved post-cracking tensile strength of the concrete results in an improved shear capacity of SFRC members. Because of this, the use of SFRC helps to meet the minimum shear reinforcement requirements in structural concrete members; and it also helps to reduce the consumption of the conventional tension steel required in the form of stirrups. The present chapter discusses various factors that influence the shear capacity of SFRC members. Different design concepts and procedures recommended by various guidelines for the shear design of SFRC members are also presented along with a typical set of the examples.
