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 30 x 30 x 3 EA the computed area agrees with the published value to 0.29% 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 | 635 mm³ |
| Elastic modulus, Zy | 635 mm³ |
| Plastic modulus, Sx | 1,182 mm³ |
| Plastic modulus, Sy | 1,182 mm³ |
| Radius of gyration, rx | 8.9 mm |
| Radius of gyration, ry | 8.9 mm |
| Principal maximum, Imax (derived) | 21,811 mm⁴ |
| Principal minimum, Imin (derived) | 5,730 mm⁴ |
| Principal axis angle, θp | 45.0° |
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.
