WT9X38

Structural Tee (from W) · AISC Shapes Database v15.0 · United States

WT9X38 is a structural tee cut from a W-shape 231.4 mm deep with a 279.4 mm wide flange, weighing 56.6 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 WT9X38 the computed area is 0.36% from published and I_x 0.09%. Where a value is also published, the published one above is the one to quote.

Property	Value
Elastic modulus, S_x	161,142 mm³
Elastic modulus, S_y	224,856 mm³
Plastic modulus, Z_x	283,353 mm³
Plastic modulus, Z_y	343,275 mm³
Radius of gyration, rx	64.7 mm
Radius of gyration, ry	66.3 mm

S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
