W40×593 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.
W40×593 measures 43 in. deep with a 16 3/4 in. flange, on a 1 13/16 in. web and 3 1/4 in. flanges.
At 593 lb per foot it is one of the 24 W40 sizes, which run from 149 to 655 lb/ft.
For strong-axis bending its section modulus is Sx = 2340 in³ and its moment of inertia Ix = 50400 in⁴, with a plastic modulus Zx = 2760 in³.
