— Concrete Shear Capacity — One-Way & Two-Way (ACI 318)
Concrete shear strength of non-prestressed members without shear reinforcement: one-way (beam) shear φVc = φ·0.17λ√f'c·bwd (ACI 318-19 §22.5) and two-way (punching) shear at a slab–column connection (§22.6), taking the least of the three code expressions. φ = 0.75.
