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 488x300x11x18 the computed area agrees with the published value to better than 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 | 2,822,553 mm³ |
| Elastic modulus, Zy | 540,410 mm³ |
| Plastic modulus, Zpx | 3,132,697 mm³ |
| Plastic modulus, Zpy | 824,914 mm³ |
| Radius of gyration, rx | 208.0 mm |
| Radius of gyration, ry | 71.4 mm |
Z is the elastic modulus and Zp the plastic modulus, following Japanese practice.
