W33×241 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.

W33×241 measures 34 1/8 in. deep with a 15 7/8 in. flange, on a 13/16 in. web and 1 3/8 in. flanges.

At 241 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 = 831 in³ and its moment of inertia Ix = 14200 in⁴, with a plastic modulus Zx = 940 in³.
