W10×100 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.

W10×100 measures 11 1/8 in. deep with a 10 3/8 in. flange, on a 11/16 in. web and 1 1/8 in. flanges.

At 100 lb per foot it is one of the 18 W10 sizes, which run from 12 to 112 lb/ft.

For strong-axis bending its section modulus is Sx = 112 in³ and its moment of inertia Ix = 623 in⁴, with a plastic modulus Zx = 130 in³.
