WT4×5 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.
WT4×5 measures 3 7/8 in. deep with a 4 in. flange, on a 3/16 in. web and 3/16 in. flanges.
At 5 lb per foot it is the lightest of the 13 WT4 sizes, which run from 5 to 33.5 lb/ft.
For strong-axis bending its section modulus is Sx = 0.717 in³ and its moment of inertia Ix = 2.15 in⁴, with a plastic modulus Zx = 1.27 in³.
