StructureCalcs400WC328
Welded Column · AS/NZS 3679.2 · Australia / New Zealand
400WC328 is a welded column 430.0 mm deep with a 400.0 mm wide flange, weighing 328.1 kg/m. The dimensions below are the published AS/NZS 3679.2 values; the drawing is generated from them.
Welded Columns extend the UC range the same way — three-plate sections for heavy column and transfer applications.

Derived section properties
Integrated from the section's exact plate outline — a welded section has square corners by construction, so nothing is approximated. For 400WC328 the computed area agrees to better than 0.01% and Ix to better than 0.01%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 6,144,690 mm³ |
| Elastic modulus, Zy | 2,136,535 mm³ |
| Plastic modulus, Sx | 7,097,500 mm³ |
| Plastic modulus, Sy | 3,268,600 mm³ |
| Radius of gyration, rx | 177.8 mm |
| Radius of gyration, ry | 101.1 mm |
Z is the elastic modulus and S the plastic modulus, following AS 4100. Under AISC 360 the letters are reversed.
