Structural Tee (from W) · AISC Shapes Database v15.0 · United States
WT7X105.5 is a structural tee cut from a W-shape 199.6 mm deep with a 401.3 mm wide flange, weighing 157.0 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 WT7X105.5 the computed area is 0.58% from published and Ix 0.33%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 264,743 mm³ |
| Elastic modulus, Sy | 1,064,543 mm³ |
| Plastic modulus, Zx | 545,183 mm³ |
| Plastic modulus, Zy | 1,620,061 mm³ |
| Radius of gyration, rx | 46.1 mm |
| Radius of gyration, ry | 103.6 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
