RC column design - Fundamental Question
(OP)
How can I determine the N.A (neutral axis)of a rectanular column with bars in all 4 faces? It is different from beam, I cannot set C = T to evaluate the N.A, there is axial force, unlike beam? In addition, since there is axial force n bending, do I just refer to N.A or the plastic centroid still play a role? I am confused. I thought I only consider plastic centroid when the section is in uniform compression.
Thank you for your help!

Try to get ahold of the PCA's Notes on ACI 318. It has some good information on column axial-bending capacities and will help you understand how to apply a strain-compatibility analysis properly. It's not exhaustive though so you will have work to do to understand more than just basics.

May I know what is PCA stand for. I think ACI 318 is American Code, right? When u mentioned it is a note, could you please tell which chapter or sections or pages, so I may find a copy from library in Australia.
Thanks alot.
