How does one design a column which has been divided into two (or more) columns in the analysis module (because of connecting beams mid-height in column, or column spanning multiple stories)  in the RC design module.  

I assume you can take a section and input the real length of the column in the buckling analysis but how does one factor in columns end moments, etc.??

[#2]

You have to divide such column into parts.

So if I have say a 6m column divided into 2 parts for analysis.  In designing the column I will design both parts as separate columns and enter efffective length  factor * 6m as the buckling length for each part ?

Decision is yours but IMHO if you are talking about right hand side case (below) I would suggest to use 3m as column length. Left => 6m.

Thanks Was talking about LHS case

How did you get buckling shapes to show?
