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 350x350x12x19 the computed area agrees with the published value to 0.01% and Ix to 0.12%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 2,276,931 mm³ |
| Elastic modulus, Zy | 776,161 mm³ |
| Plastic modulus, Zpx | 2,515,392 mm³ |
| Plastic modulus, Zpy | 1,176,274 mm³ |
| Radius of gyration, rx | 152.3 mm |
| Radius of gyration, ry | 88.9 mm |
Z is the elastic modulus and Zp the plastic modulus, following Japanese practice.
