W27×84 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.
W27×84 measures 26 3/4 in. deep with a 10 in. flange, on a 7/16 in. web and 5/8 in. flanges.
At 84 lb per foot it is the lightest of the 17 W27 sizes, which run from 84 to 539 lb/ft.
For strong-axis bending its section modulus is Sx = 213 in³ and its moment of inertia Ix = 2850 in⁴, with a plastic modulus Zx = 244 in³.
