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 912x302x18x34 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, Zx | 10,768,955 mm³ |
| Elastic modulus, Zy | 1,036,700 mm³ |
| Plastic modulus, Zpx | 12,338,355 mm³ |
| Plastic modulus, Zpy | 1,622,500 mm³ |
| Radius of gyration, rx | 369.3 mm |
| Radius of gyration, ry | 65.9 mm |
Z is the elastic modulus and Zp the plastic modulus, following Japanese practice.
