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 65 x 65 x 8 EA the computed area agrees with the published value to better than 0.01% 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 | 8,068 mm³ |
| Elastic modulus, Zy | 8,068 mm³ |
| Plastic modulus, Sx | 14,626 mm³ |
| Plastic modulus, Sy | 14,626 mm³ |
| Radius of gyration, rx | 19.7 mm |
| Radius of gyration, ry | 19.7 mm |
| Principal maximum, Imax (derived) | 589,168 mm⁴ |
| Principal minimum, Imin (derived) | 153,663 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.
