RC Shear Wall

In-plane shear and reinforcement check for cast-in-place concrete shear walls per ACI 318 §11.5 with boundary element flag.

Inputs

Method — ACI 318 §11.5
  • Vc = 0.17·λ·√f'c·tw·d (simplified); d = 0.8·Lw.
  • Vs = ρt·fy·tw·d. φVn = φ(Vc+Vs); φ = 0.75; ≤ 0.83·√f'c·tw·d.
  • ρt,min = 0.0025; ρl,min = 0.0025 (0.0015 if controlled).
  • Boundary element required when c > Lw/600·(δu/hw)⁻¹ (ACI 318 §18.10.6) — flagged when ρl > 0.01.
