Flange Line Load due to Roller

[lancer360]

I need some help finding some reference material on how to calculate the stress in the flange of a c-channel due to a roller. We are using a c-channel made from plate as a track with a straight roller pressing on the flange. I'm concerned with the stress on the flange causing a failure and the door dropping.

AISC ASD version, section K1.2 addresses local flange bending.
