W27×161 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.

W27×161 measures 27 5/8 in. deep with a 14 in. flange, on a 11/16 in. web and 1 1/16 in. flanges.

At 161 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 = 458 in³ and its moment of inertia Ix = 6310 in⁴, with a plastic modulus Zx = 515 in³.
