W36×256 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.
W36×256 measures 37 3/8 in. deep with a 12 1/4 in. flange, on a 15/16 in. web and 1 3/4 in. flanges.
At 256 lb per foot it is one of the 29 W36 sizes, which run from 135 to 925 lb/ft.
For strong-axis bending its section modulus is Sx = 895 in³ and its moment of inertia Ix = 16800 in⁴, with a plastic modulus Zx = 1040 in³.
