WT7×66 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.

WT7×66 measures 7 1/4 in. deep with a 14 3/4 in. flange, on a 5/8 in. web and 1 in. flanges.

At 66 lb per foot it is one of the 38 WT7 sizes, which run from 11 to 436.5 lb/ft.

For strong-axis bending its section modulus is Sx = 9.57 in³ and its moment of inertia Ix = 57.8 in⁴, with a plastic modulus Zx = 18.6 in³.
