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 L7X4X5/8 the computed area is 0.10% from published and Ix 0.01%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 117,036 mm³ |
| Elastic modulus, Zy | 42,302 mm³ |
| Plastic modulus, Sx | 206,537 mm³ |
| Plastic modulus, Sy | 77,754 mm³ |
| Radius of gyration, rx | 56.8 mm |
| Radius of gyration, ry | 27.9 mm |
| Principal maximum, Imax (derived) | 14,730,877 mm⁴ |
| Principal minimum, Imin (derived) | 2,018,824 mm⁴ |
| Principal axis angle, θp | 18.2° |
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.
