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 125x125x6.5x9 the computed area agrees with the published value to 0.01% and Ix to 0.04%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 135,579 mm³ |
| Elastic modulus, Zy | 46,960 mm³ |
| Plastic modulus, Zpx | 153,505 mm³ |
| Plastic modulus, Zpy | 71,913 mm³ |
| Radius of gyration, rx | 52.9 mm |
| Radius of gyration, ry | 31.1 mm |
Z is the elastic modulus and Zp the plastic modulus, following Japanese practice.
