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 45 x 45 x 3 EA the computed area agrees with the published value to 0.19% and Ix to 0.02%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 1,510 mm³ |
| Elastic modulus, Zy | 1,510 mm³ |
| Plastic modulus, Sx | 2,773 mm³ |
| Plastic modulus, Sy | 2,773 mm³ |
| Radius of gyration, rx | 13.8 mm |
| Radius of gyration, ry | 13.8 mm |
| Principal maximum, Imax (derived) | 79,009 mm⁴ |
| Principal minimum, Imin (derived) | 20,567 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.
