Root Radius of a Steel Angle

[oengineer]

I am trying to determine the "root radius" of a L5x5x7/8 member but I am not seeing it shown in AISC.

Comments/suggestions are appreciated.

k-t=1.375-.875=0.5"

If I remember right, the tabulated dimensions are based on the largest possible radius, and cross-sectional design properties are based on the smallest possible radius- so if you start calculating area properties, you may need to fudge that radius a bit to make it work. Also have some rounding going on with wide-flange beams.
