S24×106 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.

S24×106 measures 24 1/2 in. deep with a 7 7/8 in. flange, on a 5/8 in. web and 1 1/16 in. flanges.

At 106 lb per foot it is one of the 5 S24 sizes, which run from 80 to 121 lb/ft.

For strong-axis bending its section modulus is Sx = 240 in³ and its moment of inertia Ix = 2940 in⁴, with a plastic modulus Zx = 279 in³.
