Round reinforced concrete column interaction diagram

Dear Sir or Miss,

I just need to create a round reinforced concrete column interaction diagram given the column diameter and reinforcement (no. bars, bar size, and cover). Never heard of RAM and not sure if I need it.  Please call me at cell (954)817-4265 or email me at roberto.rubio@kci.com. I'll greatly appreciate the support or redirection.

Thank you

Roberto
