WT15×45 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.
WT15×45 measures 14 3/4 in. deep with a 10 3/8 in. flange, on a 1/2 in. web and 5/8 in. flanges.
At 45 lb per foot it is the lightest of the 16 WT15 sizes, which run from 45 to 195.5 lb/ft.
For strong-axis bending its section modulus is Sx = 27.1 in³ and its moment of inertia Ix = 290 in⁴, with a plastic modulus Zx = 49 in³.
