ST9×35 tee (cut from a standard beam)

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.

ST9×35 measures 9 in. deep with a 6 1/4 in. flange, on a 11/16 in. web and 11/16 in. flanges.

At 35 lb per foot it is the heaviest of the 2 ST9 sizes, which run from 27.35 to 35 lb/ft.

For strong-axis bending its section modulus is Sx = 14 in³ and its moment of inertia Ix = 84.5 in⁴, with a plastic modulus Zx = 25.1 in³.
