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 H 248x124x5x8 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, Zx | 278,225 mm³ |
| Elastic modulus, Zy | 41,060 mm³ |
| Plastic modulus, Zpx | 311,635 mm³ |
| Plastic modulus, Zpy | 63,190 mm³ |
| Radius of gyration, rx | 103.8 mm |
| Radius of gyration, ry | 28.2 mm |
Z is the elastic modulus and Zp the plastic modulus, following Japanese practice.
