2L8×8×3/4×3/4 double angle

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.

2L8×8×3/4×3/4 has equal 8 in. legs, 3/4 in. thick, spaced 3/4 in. back to back.

At 77.8 lb per foot it is one of the 21 2L8×8 sizes, which run from 52.8 to 114 lb/ft.

For strong-axis bending its section modulus is Sx = 24.4 in³ and its moment of inertia Ix = 140 in⁴, with a plastic modulus Zx = 44 in³.
