WT8×50 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.

WT8×50 measures 8 3/8 in. deep with a 10 3/8 in. flange, on a 9/16 in. web and 1 in. flanges.

At 50 lb per foot it is the heaviest of the 11 WT8 sizes, which run from 13 to 50 lb/ft.

For strong-axis bending its section modulus is Sx = 11.4 in³ and its moment of inertia Ix = 76.8 in⁴, with a plastic modulus Zx = 20.7 in³.
