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 198 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 | 3,025,990 mm³ |
| Elastic modulus, Wel,y | 1,000,699 mm³ |
| Plastic modulus, Wpl,x | 3,479,119 mm³ |
| Plastic modulus, Wpl,y | 1,530,181 mm³ |
| Radius of gyration, rx | 143.4 mm |
| Radius of gyration, ry | 77.9 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
