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 HEB 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 | 3,550,559 mm³ |
| Elastic modulus, Wel,y | 781,422 mm³ |
| Plastic modulus, Wpl,x | 3,982,370 mm³ |
| Plastic modulus, Wpl,y | 1,197,656 mm³ |
| Radius of gyration, rx | 191.4 mm |
| Radius of gyration, ry | 73.3 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
