W30×235 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.
W30×235 measures 31 1/4 in. deep with a 15 in. flange, on a 13/16 in. web and 1 1/2 in. flanges.
At 235 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 = 748 in³ and its moment of inertia Ix = 11700 in⁴, with a plastic modulus Zx = 847 in³.
