WT18×151 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.
WT18×151 measures 18 5/8 in. deep with a 16 5/8 in. flange, on a 15/16 in. web and 1 11/16 in. flanges.
At 151 lb per foot it is one of the 29 WT18 sizes, which run from 67.5 to 462.5 lb/ft.
For strong-axis bending its section modulus is Sx = 88.8 in³ and its moment of inertia Ix = 1280 in⁴, with a plastic modulus Zx = 158 in³.
