WT7×15 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.
WT7×15 measures 6 7/8 in. deep with a 6 3/4 in. flange, on a 1/4 in. web and 3/8 in. flanges.
At 15 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 = 3.55 in³ and its moment of inertia Ix = 19 in⁴, with a plastic modulus Zx = 6.25 in³.
