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 260 x 142 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 | 1,750,467 mm³ |
| Elastic modulus, Wel,y | 621,565 mm³ |
| Plastic modulus, Wpl,x | 2,015,305 mm³ |
| Plastic modulus, Wpl,y | 950,478 mm³ |
| Radius of gyration, rx | 116.2 mm |
| Radius of gyration, ry | 67.6 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
