WebOne Way Slab Reinforcement Calculation: For one way slab, main reinforcement is computed by a formula (In limit state design) that is determined by comparing compressive force as well as tensile forces. Ast = 0.5 Fck/Fu [1-√1-2.6Mu/Fck.b.d]b.d and the distribution steel is computed as 0.15% of Ag, for mild steel. 0.12% of Ag, for tor steel.
