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 W18X130 the computed area is 0.01% from published and Ix 0.58%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 4,201,700 mm³ |
| Elastic modulus, Zy | 823,477 mm³ |
| Plastic modulus, Sx | 4,770,427 mm³ |
| Plastic modulus, Sy | 1,264,443 mm³ |
| Radius of gyration, rx | 204.4 mm |
| Radius of gyration, ry | 68.9 mm |
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.
