W24×131 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.
W24×131 measures 24 1/2 in. deep with a 12 7/8 in. flange, on a 5/8 in. web and 15/16 in. flanges.
At 131 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 = 329 in³ and its moment of inertia Ix = 4020 in⁴, with a plastic modulus Zx = 370 in³.
