HSS10×8×5/16 square/rectangular HSS tube

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.

HSS10×8×5/16 is a rectangular tube 10 in. by 8 in. with a 5/16 in. nominal wall.

At 36.1 lb per foot it is one of the 6 HSS10×8 sizes, which run from 22.18 to 67.82 lb/ft.

For strong-axis bending its section modulus is Sx = 29 in³ and its moment of inertia Ix = 145 in⁴, with a plastic modulus Zx = 34.4 in³.
