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 L4X4X7/16 the computed area is 0.41% from published and Ix 1.02%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 28,749 mm³ |
| Elastic modulus, Zy | 28,749 mm³ |
| Plastic modulus, Sx | 51,804 mm³ |
| Plastic modulus, Sy | 51,804 mm³ |
| Radius of gyration, rx | 31.1 mm |
| Radius of gyration, ry | 31.1 mm |
| Principal maximum, Imax (derived) | 3,296,996 mm⁴ |
| Principal minimum, Imin (derived) | 849,048 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.
