WT8×25 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.
WT8×25 measures 8 1/8 in. deep with a 7 1/8 in. flange, on a 3/8 in. web and 5/8 in. flanges.
At 25 lb per foot it is one of the 11 WT8 sizes, which run from 13 to 50 lb/ft.
For strong-axis bending its section modulus is Sx = 6.78 in³ and its moment of inertia Ix = 42.3 in⁴, with a plastic modulus Zx = 12 in³.
