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 L3X3X3/16 the computed area is 0.34% from published and Ix 1.78%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 7,252 mm³ |
| Elastic modulus, Zy | 7,252 mm³ |
| Plastic modulus, Sx | 13,060 mm³ |
| Plastic modulus, Sy | 13,060 mm³ |
| Radius of gyration, rx | 23.9 mm |
| Radius of gyration, ry | 23.9 mm |
| Principal maximum, Imax (derived) | 641,368 mm⁴ |
| Principal minimum, Imin (derived) | 161,853 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.
