W24×68 wide-flange 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.

W24×68 measures 23 3/4 in. deep with a 9 in. flange, on a 7/16 in. web and 9/16 in. flanges.

At 68 lb per foot it is one of the 21 W24 sizes, which run from 55 to 370 lb/ft.

For strong-axis bending its section modulus is Sx = 154 in³ and its moment of inertia Ix = 1830 in⁴, with a plastic modulus Zx = 177 in³.
