W33×141 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.

W33×141 measures 33 1/4 in. deep with a 11 1/2 in. flange, on a 5/8 in. web and 15/16 in. flanges.

At 141 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 = 448 in³ and its moment of inertia Ix = 7450 in⁴, with a plastic modulus Zx = 514 in³.
