W14×109 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.
W14×109 measures 14 3/8 in. deep with a 14 5/8 in. flange, on a 1/2 in. web and 7/8 in. flanges.
At 109 lb per foot it is one of the 38 W14 sizes, which run from 22 to 873 lb/ft.
For strong-axis bending its section modulus is Sx = 173 in³ and its moment of inertia Ix = 1240 in⁴, with a plastic modulus Zx = 192 in³.
