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 W16X57 the computed area agrees with the published value to better than 0.01% and Ix to 0.17%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 1,512,300 mm³ |
| Elastic modulus, Zy | 198,532 mm³ |
| Plastic modulus, Sx | 1,725,183 mm³ |
| Plastic modulus, Sy | 309,261 mm³ |
| Radius of gyration, rx | 170.5 mm |
| Radius of gyration, ry | 40.7 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.
