Derived section properties
Integrated from the section's own outline including the root and toe radii, whose arcs are integrated analytically rather than approximated by facets. For HP 400 x 231 the computed area agrees with the published value to better than 0.01% and Ix to 0.49%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Wel,x | 3,777,494 mm³ |
| Elastic modulus, Wel,y | 1,403,169 mm³ |
| Plastic modulus, Wpl,x | 4,312,648 mm³ |
| Plastic modulus, Wpl,y | 2,158,137 mm³ |
| Radius of gyration, rx | 154.5 mm |
| Radius of gyration, ry | 97.9 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
