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 120 the computed area agrees with the published value to 0.02% 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 | 106,342 mm³ |
| Elastic modulus, Wel,y | 38,483 mm³ |
| Plastic modulus, Wpl,x | 119,491 mm³ |
| Plastic modulus, Wpl,y | 58,853 mm³ |
| Radius of gyration, rx | 48.9 mm |
| Radius of gyration, ry | 30.2 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
