W27×307 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.

W27×307 measures 29 5/8 in. deep with a 14 1/2 in. flange, on a 1 3/16 in. web and 2 1/16 in. flanges.

At 307 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 = 887 in³ and its moment of inertia Ix = 13100 in⁴, with a plastic modulus Zx = 1030 in³.
