W27×336 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.
W27×336 measures 30 in. deep with a 14 1/2 in. flange, on a 1 1/4 in. web and 2 1/4 in. flanges.
At 336 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 = 972 in³ and its moment of inertia Ix = 14600 in⁴, with a plastic modulus Zx = 1130 in³.
