From designation to geometry

Reading the WT4X29 record

The WT designation identifies a tee depth series and nominal weight per foot. Use its own tabulated depth d = 4.38 in and flange width bf = 8.22 in rather than halving every dimension of another member.

This tee has web or stem thickness tw = 0.51 in, flange thickness tf = 0.81 in and centroid distance y = 0.874 in. Stem and flange orientation matter when matching the table's axes to a model.

Ix = 9.12 in⁴ and Iy = 37.5 in⁴ refer to the database x- and y-axes. Here Iy is numerically larger. Axis letters are labels, not a guarantee that x is always the larger axis. These are geometric properties, not allowable loads or complete member capacities.

Match the axis and dimension conventions to the figures in the AISC v16.0 workbook Readme. The profile above simplifies manufacturing geometry; its outline is not used to recalculate the published properties.

Worked quantity example

Nominal weight for WT4X29

Assume 3 pieces, each 20 ft (6.096 m) long. This is a hypothetical quantity example, not a stock-length or lifting recommendation.

Using the published 29 lb/ft weight
Quantity	Calculation	Nominal pounds	Kilogram equivalent
One 20 ft piece	20 ft × 29 lb/ft	580 lb	263.084 kg
3 pieces	3 × 580 lb	1,740 lb	789.251 kg

Conversion: 1 lb = 0.45359237 kg; displayed results are rounded. This multiplication excludes connection plates, bolts, weld metal, coatings, cutting allowances and actual material variation. Use the material takeoff for your own lengths and quantities.

Shape family context

What is a structural tee cut from a W-shape?

A WT is a structural tee produced from a W-shape. It has one flange and a stem, so its properties, shear center, connection behavior, and fabrication orientation differ from the parent wide-flange section.

Common context

Common project roles include truss members, lintels, chords, edge members, reinforcement, hangers, and connection components.

Detailing watch

Confirm stem orientation, flange side, cut geometry, residual deformation, connection eccentricity, cope or weld access, and whether the specified tee is available as required.

Compare published reference values

WT4X29 alongside nearby WT records

These records share the same nominal series, outside envelope or leg arrangement, depending on the family. Peers are ordered by absolute weight difference, then listed depth and designation. The table does not rank structural performance or approve a substitution.

US customary values from the same AISC v16.0 dataset
Record	Weight (lb/ft)	Depth (in)	Area (in²)	Ix (in⁴)	Iy (in⁴)
WT4X29 (this record)	29	4.38	8.54	9.12	37.5
WT4X33.5	33.5	4.5	9.84	10.9	44.3
WT4X24	24	4.25	7.05	6.85	30.5

Relative to WT4X29, WT4X33.5 changes nominal weight by +4.5 lb/ft, listed depth by +0.12 in, and area by +1.3 in². At the same hypothetical 20 ft length, the nominal weight difference is +90 lb.

Reference use only.

Data is derived from the AISC Shapes Database v16.0, consistent with the AISC Steel Construction Manual, 16th Edition, 1st Printing. AISC advises professional verification before use in a specific application. The downloadable DXF is a nominal reference profile and may simplify rolled fillets, flange tapers, angle radii, HSS corner radii, and other manufacturing geometry. Verify all dimensions and suitability before design, detailing, ordering, or fabrication.
