Derived section properties
Integrated from the section's own outline including the root and toe radii, whose arcs are integrated analytically rather than approximated by facets. For W8X24 the computed area agrees with the published value to 0.01% and Ix to 0.10%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 342,147 mm³ |
| Elastic modulus, Zy | 92,391 mm³ |
| Plastic modulus, Sx | 379,403 mm³ |
| Plastic modulus, Sy | 140,681 mm³ |
| Radius of gyration, rx | 86.9 mm |
| Radius of gyration, ry | 40.9 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.
