Pca Notes On Aci 31819 !link! [2026]

Design a rectangular beam for flexure and shear.

ACI 318-19 increased the minimum reinforcement required for beams and one-way slabs to control cracking. The PCA Notes provide corrected tables comparing the old 200/fy formula with the new, more rational 0.5√(f'c)/fy requirement, showing exactly when the new rule governs. pca notes on aci 31819
