L5×5×3/4 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.

L5×5×3/4 has equal 5 in. legs, 3/4 in. thick.

At 23.6 lb per foot it is one of the 7 L5×5 sizes, which run from 10.3 to 27.2 lb/ft.

For strong-axis bending its section modulus is Sx = 4.52 in³ and its moment of inertia Ix = 15.7 in⁴, with a plastic modulus Zx = 8.14 in³.
