my question is how to model a rotational spring at joint center (the intersection of beam and column elements) with rigid offset?
while zerolength element requires two nodes as input arguments,
for exterior joint there are 5 nodes and for interior there are 6 nodes
how to connect the zerolength elements to those nodes and,
what are the nodes and corresponding dof to be fixed?

problem in "beamcolumn joint" element in 3D
Dear opensees user/developer
I have a problem when defining beamclumn joint element in a 3D problem for dynamic analysis..
First, how to model interior or even exterior joint in 3D, I know load is transferred only in plane, so, does that mean I have to model two joint element for each connection, one in XZ and one in YZ plane? this means I will model the element twice..
How to connect other beams perpendicular to joint plane?
Then, I encountered some issues when defining the bar-slip material such as the str parameter of "damag1" or "damage2" instead of "damage"
,and the number of parameters included in the bar-slip material to be either 13 or 15 . . .
I searched about any example for modeling joint in 3d, but nothing..
there is a single example that written in tcl to model joint in 2D, and apply static loads, but even this example is not up-to-date, and suffer some issues
any recommendations?

M-C analysis in same problem script
Hello
I am performing gravity analysis on a 3D system and I need to perform M-C analysis for RC section in the same model (same script), but I could not since main model has 6 dimensions and section analysis problem has 3D
is it possible to perform M-C analysis for RC section for a problem in the same script?

Dear Ziad
I am trying importing Vfo in jupyter, but it gives ne error:
Do you have advice on how to import it succesfully?
the error is:
ValueError: Invalid Jupyter notebook plotting backend "panel".
Use one of the following:
"static", "client", "server", "trame", "none"
