W8×35 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.
W8×35 measures 8 1/8 in. deep with a 8 in. flange, on a 5/16 in. web and 1/2 in. flanges.
At 35 lb per foot it is one of the 13 W8 sizes, which run from 10 to 67 lb/ft.
For strong-axis bending its section modulus is Sx = 31.2 in³ and its moment of inertia Ix = 127 in⁴, with a plastic modulus Zx = 34.7 in³.
