Hi everybody
I want to model the frame with beam column connections that are release for moment. how can i do that?

You need to define two nodes with the same coordinates and to use equalDOF command (http://opensees.berkeley.edu/wiki/index ... OF_command) to constrain translational dofs to each other.

For example:

node 10 0.0 0.0
node 20 0.0 0.0
equalDOF 10 20 1 2

tnx vesna, I did that and worked correctly
