WT9×65 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.
WT9×65 measures 9 5/8 in. deep with a 11 1/8 in. flange, on a 11/16 in. web and 1 3/16 in. flanges.
At 65 lb per foot it is one of the 23 WT9 sizes, which run from 17.5 to 155.5 lb/ft.
For strong-axis bending its section modulus is Sx = 16.7 in³ and its moment of inertia Ix = 127 in⁴, with a plastic modulus Zx = 30.5 in³.
