WT7×13 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.

WT7×13 measures 6 7/8 in. deep with a 5 in. flange, on a 1/4 in. web and 7/16 in. flanges.

At 13 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 = 3.31 in³ and its moment of inertia Ix = 17.3 in⁴, with a plastic modulus Zx = 5.89 in³.
