# Provided Reinforcement design for divided column

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.??

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.

How did you get buckling shapes to show?
