StructureCalcsWT8X13
Structural Tee (from W) · AISC Shapes Database v15.0 · United States
WT8X13 is a structural tee cut from a W-shape 199.4 mm deep with a 139.7 mm wide flange, weighing 19.4 kg/m. The dimensions below are the published AISC Shapes Database v15.0 values; the drawing is generated from them.
WT tees are W-shapes split at mid-depth — common truss chords and hangers, tabulated for the cut section.

Derived section properties
Integrated from a square-cornered outline — the fillet radii this family really has are not drawn, so the computed values differ slightly from published. For WT8X13 the computed area is 1.74% from published and Ix 0.61%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 66,848 mm³ |
| Elastic modulus, Sy | 28,552 mm³ |
| Plastic modulus, Zx | 120,739 mm³ |
| Plastic modulus, Zy | 44,662 mm³ |
| Radius of gyration, rx | 63.2 mm |
| Radius of gyration, ry | 28.6 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
