L8×8×1 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.

L8×8×1 has equal 8 in. legs, 1 in. thick.

At 51 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 = 15.8 in³ and its moment of inertia Ix = 89.1 in⁴, with a plastic modulus Zx = 28.5 in³.
