Derived section properties
Integrated from a square-cornered outline — the fillet radii this family really has are not drawn, so the computed values differ slightly from published. For 2L8X6X7/8SLBB the computed area is 0.16% from published and Ix 0.13%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 260,152 mm³ |
| Elastic modulus, Sy | 616,332 mm³ |
| Plastic modulus, Zx | 470,407 mm³ |
| Plastic modulus, Zy | 981,743 mm³ |
| Radius of gyration, rx | 44.3 mm |
| Radius of gyration, ry | 91.9 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
