### Why do you need minimum amount of steel in concrete?Why do you need minimum amount of steel in concrete?The minimum amount of steel reinforcement is defined as that for which "peak load at first concrete cracking" and "ultimate load after steel yielding" are equal. A minimum area of reinforcement is required to control the cracking, which occurs in the concrete due to temperature, shrinkage and creep.What is the percentage of steel in reinforced concrete?ACI 318-11 Reinforced concrete beam design parameters what are the minimum and maximum percentages of steel

(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 . = 1 (0.375 d) to find As-max . The values of 1 are presented in the following Table Minimum ReinforcementAre You suprisedthe minimum and maximum percentages of reinforcement requirements also.

### Beware of Structural Designs that Use Reinforcing Steel what are the minimum and maximum percentages of steel

Jul 12, 2016reinforcement, the minimum ratio of reinforcement area to gross concrete area is 0.0018. So for a 12- inch thick by 12-inch wall or slab section, the amount of steel needed to control shrinkage and temperature cracks is 0.0018 x 12 x 12 = 0.26 in2. Thus a #5 bars which provide an area of 0.31 in2, would be needed.Design of Reinforced Concrete Beam with Minimum Steel as what are the minimum and maximum percentages of steel fy = steel yield stress y = yield strain y = 60ksi / 29,000 ksi = 0.00207 0.080 is greater than 0.00207 therefore our assumption is correct and the steel yields prior to failure.
