WT15×66 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.
WT15×66 measures 15 1/8 in. deep with a 10 1/2 in. flange, on a 5/8 in. web and 1 in. flanges.
At 66 lb per foot it is one of the 16 WT15 sizes, which run from 45 to 195.5 lb/ft.
For strong-axis bending its section modulus is Sx = 37.4 in³ and its moment of inertia Ix = 421 in⁴, with a plastic modulus Zx = 66.8 in³.
