Derived section properties
Integrated from a square-cornered outline: no root radius is published for this standard, and that is material a rolled section really has, so these run slightly below the published values. For L3X2-1/2X5/16 the computed area is 0.21% from published and Ix 0.31%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 11,296 mm³ |
| Elastic modulus, Zy | 8,111 mm³ |
| Plastic modulus, Sx | 20,478 mm³ |
| Plastic modulus, Sy | 14,586 mm³ |
| Radius of gyration, rx | 23.8 mm |
| Radius of gyration, ry | 18.9 mm |
| Principal maximum, Imax (derived) | 781,115 mm⁴ |
| Principal minimum, Imin (derived) | 186,009 mm⁴ |
| Principal axis angle, θp | 34.2° |
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.
