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 2L8X6X1LLBB the computed area is 0.76% from published and Ix 0.28%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 495,188 mm³ |
| Elastic modulus, Sy | 406,035 mm³ |
| Plastic modulus, Zx | 847,085 mm³ |
| Plastic modulus, Zy | 704,644 mm³ |
| Radius of gyration, rx | 63.3 mm |
| Radius of gyration, ry | 60.7 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
