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 152x152x23 UC the computed area agrees with the published value to 0.02% and Ix to 0.20%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 163,717 mm³ |
| Elastic modulus, Zy | 52,550 mm³ |
| Plastic modulus, Sx | 181,642 mm³ |
| Plastic modulus, Sy | 80,128 mm³ |
| Radius of gyration, rx | 65.4 mm |
| Radius of gyration, ry | 37.0 mm |
Z is the elastic modulus and S the plastic modulus, following British practice (BS 5950 notation). Under AISC 360 the letters are reversed.
