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 100 x 75 x 10 UA the computed area agrees with the published value to 0.30% and Ix to 0.13%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 22,642 mm³ |
| Elastic modulus, Zy | 13,352 mm³ |
| Plastic modulus, Sx | 41,309 mm³ |
| Plastic modulus, Sy | 24,310 mm³ |
| Radius of gyration, rx | 31.3 mm |
| Radius of gyration, ry | 21.7 mm |
| Principal maximum, Imax (derived) | 1,886,405 mm⁴ |
| Principal minimum, Imin (derived) | 401,377 mm⁴ |
| Principal axis angle, θp | 28.6° |
Z is the elastic modulus and S the plastic modulus, following AS 4100. Under AISC 360 the letters are reversed — S is elastic and Z is plastic.
