ACI 318 - 11: Reinforced concrete beam design parameters Reinforcement Ratio The amount of steel reinforcement in concrete members should be limited. Over-reinforcing (the placement of too much reinforcement) will not allow the steel to yield before the concrete crushes and there is a sudden failure. The reinforcement ratio in concrete beam design is th following fraction: The reinforcement ratio, ρ, must be less than a value determined with a concrete strain of 0.003 and tensile strain of 0.004 (minimum). Crack Width Calculation Ec2000When the strain in the reinforcement is 0.005 or greater, the section is tension controlled. (For smaller strains the resistance factor reduces to 0.65 because the stress is less than the yield stress in the steel.) Maximum Reinforcement Based on the limiting strain of 0.005 in the steel, x(or c) = 0.375d so α = β 1 (0.375 d) to find As-max The values of β 1 are presented in the following Table: Minimum Reinforcement Minimum reinforcement is provided even if the concrete can resist the tension, in order to control cracking. Minimum required reinforcement: but not less than where: f y is the yield strength in psi b w is the width of the web of a concrete T-Beam cross section d is the effective depth from the top of a reinforced concrete beam to the centroid of the tensile steel Cover for Reinforcement Cover of concrete over/under the reinforcement must be provided to protect the steel from corrosion. For indoor exposure, 1.5 inch is typical for beams and columns, 0.75 inch is typical for slabs, and for concrete cast against soil, 3 inch minimum is required. Bar Spacing Minimum bar spacings are specified to allow proper consolidation of concrete around the reinforcement. The minimum spacing is the maximum of 1 in, a bar diameter, or 1.33 times the maximum aggregate size. Effective width b eff In case of T- Beams or Gamma-Beams, the effective slab can be calculated as follows: For interior T-sections, b eff is the smallest of: L/4, bw + 16t, or center to center of beams For exterior T-sections, bE is the smallest of bw + L/12, bw + 6t, or bw + ½(clear distance to next beam) When the web is in tension the minimum reinforcement required is the same as for rectangular sections with the web width ( bw) in place of b.
