W30×357 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.
W30×357 measures 32 3/4 in. deep with a 15 1/2 in. flange, on a 1 1/4 in. web and 2 1/4 in. flanges.
At 357 lb per foot it is one of the 16 W30 sizes, which run from 90 to 391 lb/ft.
For strong-axis bending its section modulus is Sx = 1140 in³ and its moment of inertia Ix = 18700 in⁴, with a plastic modulus Zx = 1320 in³.
