HSS14×8×5/16 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.

HSS14×8×5/16 is a rectangular tube 14 in. by 8 in. with a 5/16 in. nominal wall.

At 44.6 lb per foot it is one of the 6 HSS14×8 sizes, which run from 27.29 to 84.84 lb/ft.

For strong-axis bending its section modulus is Sx = 46.5 in³ and its moment of inertia Ix = 325 in⁴, with a plastic modulus Zx = 56.6 in³.
