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 L4X3-1/2X1/2 the computed area is better than 0.01% from published and Ix 0.05%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 31,719 mm³ |
| Elastic modulus, Zy | 24,854 mm³ |
| Plastic modulus, Sx | 57,355 mm³ |
| Plastic modulus, Sy | 44,808 mm³ |
| Radius of gyration, rx | 31.3 mm |
| Radius of gyration, ry | 26.4 mm |
| Principal maximum, Imax (derived) | 3,035,021 mm⁴ |
| Principal minimum, Imin (derived) | 758,755 mm⁴ |
| Principal axis angle, θp | 36.9° |
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.
