WT4X29

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

WT4X29 is a structural tee cut from a W-shape 111.3 mm deep with a 208.8 mm wide flange, weighing 43.2 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 WT4X29 the computed area is 0.74% from published and I_x 0.35%. Where a value is also published, the published one above is the one to quote.

Property	Value
Elastic modulus, S_x	42,792 mm³
Elastic modulus, S_y	149,609 mm³
Plastic modulus, Z_x	85,756 mm³
Plastic modulus, Z_y	227,980 mm³
Radius of gyration, rx	26.4 mm
Radius of gyration, ry	53.4 mm

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