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 HP 320 x 88 the computed area agrees with the published value to better than 0.01% and Ix to 0.01%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Wel,x | 1,237,142 mm³ |
| Elastic modulus, Wel,y | 370,630 mm³ |
| Plastic modulus, Wpl,x | 1,378,613 mm³ |
| Plastic modulus, Wpl,y | 572,069 mm³ |
| Radius of gyration, rx | 129.0 mm |
| Radius of gyration, ry | 70.7 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
