Title: Minimum Flexure and Shear Reinforcement for HSFRC

Abstract:Two-point loading tests were conducted to examine the shear and flexural behavior of High Strength Steel Fiber Reinforced Concrete (HSFRC) elements with a minimum amount of reinforcement. In shear, considerations of the ratio between the capacity that is required of the minimum shear reinforcement and the concrete shear capacity Vc show that the requirement for minimum reinforcement may depend on the definition of Vc, i.e., whether it is that of the plain concrete or that of a concrete mix, which includes the fibers. In flexure, the addition of fibers to flexural members with a minimum longitudinal reinforcement caused in the current study a more brittle behavior compared to the same specimens, which did not include fibers. This result suggests that the minimum longitudinal reinforcement ratio in flexural HSFRC members should be higher than in conventionally reinforced members (i.e., without fibers) in order to achieve sufficient ductility.
