WT3×10 tee (cut from a wide-flange)

Detailing dimensions and section properties from the AISC Shapes Database, 16th Edition. Values are shown to the nearest 1/16 in. as they appear on a shop drawing.

WT3×10 measures 3 in. deep with a 6 in. flange, on a 1/4 in. web and 3/8 in. flanges.

At 10 lb per foot it is one of the 7 WT3 sizes, which run from 4.25 to 12.5 lb/ft.

For strong-axis bending its section modulus is Sx = 0.693 in³ and its moment of inertia Ix = 1.76 in⁴, with a plastic modulus Zx = 1.29 in³.
