W27×539 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.
W27×539 measures 32 1/2 in. deep with a 15 1/4 in. flange, on a 2 in. web and 3 9/16 in. flanges.
At 539 lb per foot it is the heaviest of the 17 W27 sizes, which run from 84 to 539 lb/ft.
For strong-axis bending its section modulus is Sx = 1570 in³ and its moment of inertia Ix = 25600 in⁴, with a plastic modulus Zx = 1890 in³.
