L8×8×7/8 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.
L8×8×7/8 has equal 8 in. legs, 7/8 in. thick.
At 45 lb per foot it is one of the 7 L8×8 sizes, which run from 26.4 to 56.9 lb/ft.
For strong-axis bending its section modulus is Sx = 14 in³ and its moment of inertia Ix = 79.7 in⁴, with a plastic modulus Zx = 25.3 in³.
