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 ISMC 150 the computed area agrees with the published value to 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, Zex | 104,978 mm³ |
| Elastic modulus, Zey | 19,426 mm³ |
| Plastic modulus, Zpx | 121,382 mm³ |
| Plastic modulus, Zpy | 38,437 mm³ |
| Radius of gyration, rx | 60.8 mm |
