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 HEA 450 the computed area agrees with the published value 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, Wel,x | 2,896,438 mm³ |
| Elastic modulus, Wel,y | 631,022 mm³ |
| Plastic modulus, Wpl,x | 3,215,867 mm³ |
| Plastic modulus, Wpl,y | 965,531 mm³ |
| Radius of gyration, rx | 189.2 mm |
| Radius of gyration, ry | 72.9 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
