Frame structure I never use joints - most frame software and in beam modelling one does not use that it is not a best practice and not standard in anyway.


1 D elements are connected as needed and dof are released or kept depending on their interaction at joints.


When we connect a beam and a truss they are automatically pinned at their connection since trusses do not have any rotations.


if you want to use joints then double check your results and if they are Ok I assume it is OK then.
