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 2L6X3-1/2X3/8SLBB the computed area is 0.58% from published and Ix 0.40%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 40,325 mm³ |
| Elastic modulus, Sy | 147,706 mm³ |
| Plastic modulus, Zx | 72,214 mm³ |
| Plastic modulus, Zy | 228,303 mm³ |
| Radius of gyration, rx | 25.1 mm |
| Radius of gyration, ry | 71.4 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
