ACI 318 Concrete Design Calculators
Flexure, shear, development length, columns, punching shear, slabs.
ACI 318 Concrete Design Calculators
Flexural Design (ϕMn, ρ, a)
Nominal strength, strain compatibility.
One-Way Shear (Vc + Vs)
Design Vs, spacing, θ limits.
Development & Splice Length
Ld, Ldh, top-bar, coating modifiers.
Column Interaction (P-M)
Axial-flexure strength points.
Punching Shear (Two-Way)
Vc, Vs (stud rails), perimeters.
One-Way Slab Design
ρmin/ρmax, serviceability checks.
Beam Design (Flexure + Shear)
Integrated bending & shear checks.
Deflection & Span-to-Depth
Immediate & long-term checks.
Crack Control & Spacing
Bar spacing limits & service stress.
Standards note
Verify f'c, fy, load combos (e.g., ASCE 7), detailing, and local amendments.
