W12×65 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.

W12×65 measures 12 1/8 in. deep with a 12 in. flange, on a 3/8 in. web and 5/8 in. flanges.

At 65 lb per foot it is one of the 29 W12 sizes, which run from 14 to 336 lb/ft.

For strong-axis bending its section modulus is Sx = 87.9 in³ and its moment of inertia Ix = 533 in⁴, with a plastic modulus Zx = 96.8 in³.
