WebThe reserve flexural capacity of the RC beams, P y /P cr ≥ 1.30 which satisfies the ACI 318-08 provisions; and P p /P cr is higher for RC beams with crimped fibers than specimens with hooked fibers, demonstrating the efficiency of crimped steel fiber as secondary reinforcement in RC beams (with conventional steel rebars as primary reinforcement). WebA minimum area of shear reinforcement should be provided in all regions of a beam where applied shear is greater than half the designed shear strength of concrete. The minimum shear reinforcement (A v,min) in beams should be the greater of the following: Av,min=0.062*fc'(0.5)* (bw*s/fyt) Equation 4. Av,min=0.35* (bw*s/fyt) Equation 5. bilt bluetooth helmet firmware update
