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 firstname.lastname@example.org. I'll greatly appreciate the support or redirection.
Ram Structural System or Ram Elements could help here. What design code are you in? Is there anything special about the column (like large tension)?
