2L8×8×7/8×3/8 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.

2L8×8×7/8×3/8 has equal 8 in. legs, 7/8 in. thick, spaced 3/8 in. back to back.

At 90 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 = 28 in³ and its moment of inertia Ix = 159 in⁴, with a plastic modulus Zx = 50.6 in³.
