To specify member end releases

To release one or both ends of a member in one or more degrees of freedom, use the following procedure.

Member ends are assumed fixed against translation and rotation with respect to their end nodes. In order to change this condition, you must specify the end releases.

Select the members which will all have the same end releases.
Note: If you are applying release conditions to only one end, you must select the node for that end as well.

On the Member ribbon tab, select one of the member release tools in the Edit group:
