Column Interaction Diagrams 2

[Anzoz]

Hello,

Does anyone know where I can find a interaction diagram (curve) database where I can find interaction diagrams for different strength of concrete and steel. Or if someone can help me find a good program or website that can draw interaction diagrams or let me input the column data and give me the optimal reinforcement ratio.

Thanks

CRSI used to publish handbooks that gave column allowables at all the points of interest (no compression, no moment, balance point, etc.) for a myriad of combinations of shape, concrete allowables and reinforcing. I'm not sure they're kept up to date anymore, but you can easily assemble the curves from these tables.

CRSI / ACI handbooks. Also most of the text books on concrete design provide interaction diagrams.
I am sure if you Google, you would find some design aids.
