Column Rebar Calculator (per 1 meter)
Multi-rows. Longitudinal bars and ties/stirrups with multi-segment spacing per meter. Unit weight ≈ d²/162 (kg/m).

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

          Tie Segments (per meter run)
              Tip: Segment length is within a 1 m run (e.g., 0.2 m at 100 mm, 0.6 m at 150 mm, 0.2 m at 100 mm). Rounding mode applies to each segment.
Tie perimeter at centerline ≈ 2×[(b − 2×cover + d) + (h − 2×cover + d)] + hooks.
Grand totals include per-meter and per-meter × quantities.
