Buckling analysis of shell in Robot Structural Analysis.

Hello,

 

I would like to perform a buckling analysis of shell using Robot Structural Analysis and determine the critical loads. Is this possible?
The modes are displayed correctly, but I'm having trouble finding the critical loads.

 

Thank you for help.

Check the Critical load table. There is a value for every mode . For example a factor of 1.5 means that buckling will occur if that load case is multiplied this factor

Thank you Rafael for your anwser. 
My question relates to the fact that I obtained negative values ​​during the analysis. My interpretation of the results is that negative values ​​indicate forces leading to buckling in the opposite direction. Do you confirm this assumption?

In bucling analysis settings you can choose to show only the positive factors
