How to model the support of a gerber beam?

How to model the support of a gerber beam?

(OP)
I have a problem modeling a gerber beam of a simple metallic building.

Actually they are a group of beams, that will carry the panels, and they are supported on the beams of the frames. The first joint of each beam should connect to the frame by a pivot (the two joints should have the same deformation in X,Y and Z direction) whereas the rest of the joints should have a rolling support (same deformation only in X and Z direction). The beam in between is interrupted and all rotations are allowed, this is why i have released all the moments in each end.

I have tried using constrains ( 2 types ) but the shear force is not moddeled correctly on the beams of the frame, although the deformations work. Also i tried using links but i couldnt model the rolling support, am i doing soemthing wrong? The deformation U2 and U3 of my gerber beam would be 0 while the beam of the frame has non-zero values.

I have also set the gerber beams to have a distance of a 0.1 from the beam of the frame so i wouldn;t use offset.

I am a student asking for help,thanks in advance.
