WT12×34 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.
WT12×34 measures 11 7/8 in. deep with a 9 in. flange, on a 7/16 in. web and 9/16 in. flanges.
At 34 lb per foot it is one of the 21 WT12 sizes, which run from 27.5 to 185 lb/ft.
For strong-axis bending its section modulus is Sx = 15.6 in³ and its moment of inertia Ix = 137 in⁴, with a plastic modulus Zx = 27.9 in³.
