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 150 x 100 x 12 UA the computed area agrees with the published value to 0.11% and Ix to 0.01%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 64,641 mm³ |
| Elastic modulus, Zy | 30,890 mm³ |
| Plastic modulus, Sx | 116,742 mm³ |
| Plastic modulus, Sy | 55,955 mm³ |
| Radius of gyration, rx | 47.7 mm |
| Radius of gyration, ry | 28.6 mm |
| Principal maximum, Imax (derived) | 7,513,792 mm⁴ |
| Principal minimum, Imin (derived) | 1,346,343 mm⁴ |
| Principal axis angle, θp | 23.6° |
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.
