Bearing Wall Design Calculator

Concrete bearing wall design under primarily axial load — empirical method per ACI 318-19 §11.5.3 with slenderness and eccentricity checks

Note: This tool calculates per ACI/EIT standards but does not replace review by the design engineer.

Wall Height Lc (m)

Wall Length Lw (m)

Wall Thickness h (mm)

Slenderness ratio: kLc/h ~ 12.0 (k=0.8) → Short wall (kLc/h ≤ 25)

Resolved suite ACI_318_19 — use caller-factored actions based on 1.2D + 1.6L (ACI 318-19).

Axial Load Pu (kN)

Eccentricity e (mm)

e/h ratio: e/h = 0.1000 → Within kern (middle third)

k = 0.8 for walls braced at top and bottom; k = 1.0 if unrestrained; k = 2.0 for cantilever.
