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 340 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 | 2,156,259 mm³ |
| Elastic modulus, Wel,y | 645,996 mm³ |
| Plastic modulus, Wpl,x | 2,408,106 mm³ |
| Plastic modulus, Wpl,y | 985,721 mm³ |
| Radius of gyration, rx | 146.5 mm |
| Radius of gyration, ry | 75.3 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
