HSS8×8×1/8 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.

HSS8×8×1/8 is a square tube 8 in. by 8 in. with a 1/8 in. nominal wall.

At 13.26 lb per foot it is the lightest of the 7 HSS8×8 sizes, which run from 13.26 to 59.32 lb/ft.

For strong-axis bending its section modulus is Sx = 9.34 in³ and its moment of inertia Ix = 37.4 in⁴, with a plastic modulus Zx = 10.7 in³.
