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 158 the computed area agrees with the published value to better than 0.01% and Ix to 0.75%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Wel,x | 2,581,165 mm³ |
| Elastic modulus, Wel,y | 932,366 mm³ |
| Plastic modulus, Wpl,x | 2,888,552 mm³ |
| Plastic modulus, Wpl,y | 1,425,466 mm³ |
| Radius of gyration, rx | 151.0 mm |
| Radius of gyration, ry | 95.5 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
