2L10×10×1-1/4 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.

2L10×10×1-1/4 has equal 10 in. legs, 1 1/4 in. thick, in contact back to back.

At 160 lb per foot it is one of the 18 2L10×10 sizes, which run from 98.2 to 174 lb/ft.

For strong-axis bending its section modulus is Sx = 60.4 in³ and its moment of inertia Ix = 426 in⁴, with a plastic modulus Zx = 110 in³.
