WT7×404 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.
WT7×404 measures 11 3/8 in. deep with a 18 5/8 in. flange, on a 3 3/4 in. web and 5 1/8 in. flanges.
At 404 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 = 116 in³ and its moment of inertia Ix = 898 in⁴, with a plastic modulus Zx = 249 in³.
