W8×10 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.
W8×10 measures 7 7/8 in. deep with a 4 in. flange, on a 3/16 in. web and 3/16 in. flanges.
At 10 lb per foot it is the lightest of the 13 W8 sizes, which run from 10 to 67 lb/ft.
For strong-axis bending its section modulus is Sx = 7.81 in³ and its moment of inertia Ix = 30.8 in⁴, with a plastic modulus Zx = 8.87 in³.
