Hello everyone
I have a moment stiffness in kNm/deg from IDEA StatiCa that I need to enter in Robot for two connections to determine the buckling length. See the red-marked areas below. Can anyone help with this?
I would greatly appreciate it.
Adding rotationel stiffness in Robot and calculating buckling lenght
You can use bar releases to do that
But beware that in your model these connections/nodes are not fully rigid supports . They already have a rotation stiffness generated by the model itself.

Hello Rafa
Thank you for your response. 😊
I have now entered the stiffness and selected buckling analyses parameters under Analysis type, which provided me with some critical coefficient. However, I need to find the critical coefficient for a specific member.
How do i get that?
That is a wish that everyone performing buckling analysis want since ages ago.
only way I see is searching through the deformation modes ,the one that is mobilizing the bar you want

Hi @hsAK4KU
Before running Buckling analysis, split the yellow bar at node 6.
In the buckling analysis table right clic in the table > table columns then select the needed item
These values will give you an idea of the buckling length, but they have nothing to do with the values in the code.
