Rotational Spring

Hi

 

I need to ask for you help. I have been struggling for a long time to establish connection between to wire elements. I want to model column-beam connection. I want to apply some elastic stiffness between does two elements, some kind of rotationa spring.

Do I need to use connectors? Maybe there is some other option, because definition of connector is to hard for me.

 

I really appreciate any help. :)
