MT5×4 tee (cut from a junior 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.

MT5×4 measures 4 7/8 in. deep with a 2 3/4 in. flange, on a 1/8 in. web and 3/16 in. flanges.

At 4 lb per foot it is one of the 3 MT5 sizes, which run from 3.75 to 4.5 lb/ft.

For strong-axis bending its section modulus is Sx = 0.894 in³ and its moment of inertia Ix = 3.08 in⁴, with a plastic modulus Zx = 1.61 in³.
