W24×103 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.
W24×103 measures 24 1/2 in. deep with a 9 in. flange, on a 9/16 in. web and 1 in. flanges.
At 103 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 = 245 in³ and its moment of inertia Ix = 3000 in⁴, with a plastic modulus Zx = 280 in³.
