Retrofitted Connections for Thick Fireproofed members
(OP)
I looked through the aisc design guides for a retrofitted connection on thick fireproofed members and found nothing. Is there any resource that shows details of such?

I do not understand what you are describing in the last sentence about the shear plate connected to the column and the shear plate of the beam. Are there two shear plates? You mention 12" between the middle of the beam to the edge of the fireproofing.
A sketch would help clear up the confusion.

1) AISC's extended single shear plate connection. You can find some design information here: Link
2) A method of my own invention that I think would be preferable because it would require less concrete removal. The downside is that you may need to check the column for the moment arising from the eccentricity of the shear connection.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
