Dear STKO team, I built a simple prefabricated frame with STKO, but there was an error when running it that I did not encounter, can you tell me how to solve it?
I really need your help and it will determine whether I will be criticized for my next group meeting. Thank you!

There are some mistakes:

• Rigid Links are connected to floating nodes, and not to the beams. I merged them.

• The rigid link should be of type Beam, not bar
• Before the eigen, use a dummy analysis (0 stesp, no wipeAnalysis) to use the penalty method. You have overlapping rigidLinks and equalDOFs on same nodes
• Do the same update on the dynamic analysis

Here's a modified file

Thanks for the reply, this is so important to me, thank you!
I wonder how you do it with multiple points using the same interaction, is there a quick way to do this? I wanted to develop this structure into a multi-layered and multi-span framework, but there were so many interactions that it took me a lot of time, and it was difficult for me to spot omissions in the process.

You can simply create an interaction, select all masters, right click, select all slaves.
Just remember the rule: every slave will be attached to the nearest master
