ABSTRACT
This paper develops an equation to predict steel fiber contribution to the shear strength of steel fiber-reinforced concrete (SFRC). This equation will be used to modify the CSA A23.3-04 general shear design method and Bažant and Kim equations so that the modified relations safely predict the shear strength of SFRC without stirrups. This paper analyzes 218 shear failure tests previously conducted on SFRC without stirrups and 72 tests on reinforced concrete-with no stirrups and no steel fibers-to verify the applicability, accuracy, and efficiency of the two equations developed in this paper and five other equations from the literature. Furthermore, it shows that hooked steel fibers are not as efficient as crimped fibers, and that round fibers are among the most efficient fibers used in those tests. Moreover, it recommends a procedure to calculate steel fiber geometry factors, another factor to evaluate engineering equations, and further research on different SFRC aspects.

    An experimental study on eight large reinforced concrete deep beams was performed. The variables were the shear span-depth ratio (a/d = 1.55 or 2.29), quantity of stirrups (0.0 or 0.1%), and type of loading (monotonic or fully reversed cyclic). All members failed in shear before yielding of the...
