WT20×186 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.
WT20×186 measures 20 1/4 in. deep with a 16 1/8 in. flange, on a 1 3/16 in. web and 2 1/16 in. flanges.
At 186 lb per foot it is one of the 24 WT20 sizes, which run from 74.5 to 327.5 lb/ft.
For strong-axis bending its section modulus is Sx = 126 in³ and its moment of inertia Ix = 1930 in⁴, with a plastic modulus Zx = 225 in³.
