WT7×88 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.

WT7×88 measures 7 1/2 in. deep with a 15 5/8 in. flange, on a 13/16 in. web and 1 5/16 in. flanges.

At 88 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 = 13 in³ and its moment of inertia Ix = 80.5 in⁴, with a plastic modulus Zx = 26.3 in³.
