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 L5X3-1/2X1/2 the computed area is better than 0.01% from published and Ix 0.04%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 48,938 mm³ |
| Elastic modulus, Zy | 25,576 mm³ |
| Plastic modulus, Sx | 88,080 mm³ |
| Plastic modulus, Sy | 46,293 mm³ |
| Radius of gyration, rx | 40.1 mm |
| Radius of gyration, ry | 25.6 mm |
| Principal maximum, Imax (derived) | 4,892,388 mm⁴ |
| Principal minimum, Imin (derived) | 948,943 mm⁴ |
| Principal axis angle, θp | 25.6° |
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.
