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 HD 400 x 237 the computed area agrees with the published value to better than 0.01% and Ix to 0.45%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Wel,x | 4,146,184 mm³ |
| Elastic modulus, Wel,y | 1,571,730 mm³ |
| Plastic modulus, Wpl,x | 4,685,612 mm³ |
| Plastic modulus, Wpl,y | 2,386,991 mm³ |
| Radius of gyration, rx | 161.8 mm |
| Radius of gyration, ry | 101.6 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
