WT7×45 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.
WT7×45 measures 7 in. deep with a 14 1/2 in. flange, on a 7/16 in. web and 11/16 in. flanges.
At 45 lb per foot it is one of the 38 WT7 sizes, which run from 11 to 436.5 lb/ft.
For strong-axis bending its section modulus is Sx = 6.16 in³ and its moment of inertia Ix = 36.5 in⁴, with a plastic modulus Zx = 11.5 in³.
