W16×89 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.

W16×89 measures 16 3/4 in. deep with a 10 3/8 in. flange, on a 1/2 in. web and 7/8 in. flanges.

At 89 lb per foot it is one of the 11 W16 sizes, which run from 26 to 100 lb/ft.

For strong-axis bending its section modulus is Sx = 155 in³ and its moment of inertia Ix = 1300 in⁴, with a plastic modulus Zx = 175 in³.
