Finally, I am able to work out the buckling analysis of the column attached to rigid link. I cross checked with manual calculation the different values of buckling load factor with length variation of rigid link and it matches. Thanks a lot. The trend is that as I increase the rigid link length, the buckling load factor decreases.
Now I have to find the optimal shape i.e., the one maximizing Buckling load factor for different lengths of the rigid link. The problem is that the optimize cross-section component of Karamba is unable to choose proper cross-section sizes and hence is providing me with cross-sections that lead to buckling load factor less than 1, where it can clearly provide larger cross-sections.
I’ve attached the GH script below for your perusal.

Please kindly guide me on how to properly utilize it.
