How to Calculate Steel Quantity for Slab, Footing and ...
The same equation used for both main and shrinkage and temperature reinforcement, but corresponding cutting length, number of bars, and bar diameter is used. Main steel bars=No. of bars*cutting length*weight of the bar (/162) Equation 7 (/162) is the weight of a steel which is derived from steel volume times its density which is 7850 kg/m 3.
