W33×354 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.
W33×354 measures 35 1/2 in. deep with a 16 1/8 in. flange, on a 1 3/16 in. web and 2 1/16 in. flanges.
At 354 lb per foot it is one of the 13 W33 sizes, which run from 118 to 387 lb/ft.
For strong-axis bending its section modulus is Sx = 1240 in³ and its moment of inertia Ix = 22000 in⁴, with a plastic modulus Zx = 1420 in³.
