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 100 the computed area agrees with the published value to 0.01% and Ix to 0.46%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zex | 38,578 mm³ |
| Elastic modulus, Zey | 7,710 mm³ |
| Plastic modulus, Zpx | 45,438 mm³ |
| Plastic modulus, Zpy | 14,855 mm³ |
| Radius of gyration, rx | 39.8 mm |
| Radius of gyration, ry | 14.8 mm |
Ze is the elastic modulus and Zp the plastic modulus, following IS 800 notation.
