W27×281 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.

W27×281 measures 29 1/4 in. deep with a 14 3/8 in. flange, on a 1 1/16 in. web and 1 15/16 in. flanges.

At 281 lb per foot it is one of the 17 W27 sizes, which run from 84 to 539 lb/ft.

For strong-axis bending its section modulus is Sx = 814 in³ and its moment of inertia Ix = 11900 in⁴, with a plastic modulus Zx = 936 in³.
