WT18×116 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.

WT18×116 measures 18 1/2 in. deep with a 12 1/8 in. flange, on a 7/8 in. web and 1 9/16 in. flanges.

At 116 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 = 78.5 in³ and its moment of inertia Ix = 1080 in⁴, with a plastic modulus Zx = 140 in³.
