Derived section properties
Integrated from the section's exact plate outline — a welded section has square corners by construction, so nothing is approximated. For 350WC197 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 | 2,935,384 mm³ |
| Elastic modulus, Zy | 1,144,381 mm³ |
| Plastic modulus, Sx | 3,347,525 mm³ |
| Plastic modulus, Sy | 1,742,500 mm³ |
| Radius of gyration, rx | 139.1 mm |
| Radius of gyration, ry | 89.3 mm |
Z is the elastic modulus and S the plastic modulus, following AS 4100. Under AISC 360 the letters are reversed.
