Column Rebar Calculator — per running meter

Column Rebar Calculator (per 1 meter)

Compute weight per running meter for longitudinal bars (e.g., 4DB16) and ties/stirrups (e.g., RB6 @ 100). Unit weight ≈ d²/162 (kg/m).

Longitudinal Bars

Number of Bars (pcs)

Diameter (mm)

Length accounted (m/m)

Waste/Anchorage (%)

uw: — kg/m

Per meter of column, longitudinal length ≈ (number of bars × 1 m). Add waste/anchorage as needed.

Ties / Stirrups

Tie Dia (mm)

Spacing (mm)

Column Width b (mm)

Column Depth h (mm)

Concrete Cover (mm)

Hook length per end (mm)

Ends with hooks Both ends One end No hook

Waste for Ties (%)

uw: — kg/m

Tie perimeter at centerline ≈ 2×[(b − 2×cover + d) + (h − 2×cover + d)] + hooks.

Unit weight: d²/162 (kg/m). Ties/m ≈ 1000/spacing (ceil is conservative for BOQ).
