W24×370 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.
W24×370 measures 28 in. deep with a 13 5/8 in. flange, on a 1 1/2 in. web and 2 3/4 in. flanges.
At 370 lb per foot it is the heaviest of the 21 W24 sizes, which run from 55 to 370 lb/ft.
For strong-axis bending its section modulus is Sx = 957 in³ and its moment of inertia Ix = 13400 in⁴, with a plastic modulus Zx = 1130 in³.
