Derived section properties
Integrated from the section's exact plate outline — a welded section has square corners by construction, so nothing is approximated. For 400WC144 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 | 2,545,021 mm³ |
| Elastic modulus, Zy | 853,931 mm³ |
| Plastic modulus, Sx | 2,832,400 mm³ |
| Plastic modulus, Sy | 1,302,400 mm³ |
| Radius of gyration, rx | 162.5 mm |
| Radius of gyration, ry | 96.3 mm |
Z is the elastic modulus and S the plastic modulus, following AS 4100. Under AISC 360 the letters are reversed.
