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 HD 320 x 300 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 | 4,634,924 mm³ |
| Elastic modulus, Wel,y | 1,572,056 mm³ |
| Plastic modulus, Wpl,x | 5,521,797 mm³ |
| Plastic modulus, Wpl,y | 2,414,326 mm³ |
| Radius of gyration, rx | 150.8 mm |
| Radius of gyration, ry | 80.2 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
