W14×34 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.
W14×34 measures 14 in. deep with a 6 3/4 in. flange, on a 5/16 in. web and 7/16 in. flanges.
At 34 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 = 48.6 in³ and its moment of inertia Ix = 340 in⁴, with a plastic modulus Zx = 54.6 in³.
