Concrete Column Punching — Bulk
AS 3600:2018 Cl 9.3 · Multi-column schedule · Biaxial moment · Same engine as the single-column tool
One row = one column. Units: mm, kN, kNm, MPa. Set Shape = circ to use D as the circular diameter (L, W ignored). Negative V* / moments are taken by magnitude. Paste order matches the column order below.
