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 918x303x19x37 the computed area agrees with the published value to better than 0.01% and Ix to 0.08%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 11,665,308 mm³ |
| Elastic modulus, Zy | 1,135,857 mm³ |
| Plastic modulus, Zpx | 13,378,026 mm³ |
| Plastic modulus, Zpy | 1,778,446 mm³ |
| Radius of gyration, rx | 371.8 mm |
| Radius of gyration, ry | 66.6 mm |
Z is the elastic modulus and Zp the plastic modulus, following Japanese practice.
