Coupled Wire Beams

[Entherm]

I have two wire beams parallel to each other, they are at an angle with horizontal. I tried coupling the U2, U3, UR1, UR2, and UR3 using a local coordinate system with nodes on one beam as controlling and nodes on the other as slave. They are aligned in elastic range but seem to not move parallel to each other in non-linear range. What might be the reason for this? How can I make the beams align with each other even in non-linear range?

What exactly do you want to simulate ? Maybe one of the several connector types will let you achieve the desired goal.

I am trying to simulate the buckling of one of the beams, it has low buckling capacity. The other beam (that went out of alignment) has high buckling strength; when we use the kinematic coupling with degrees of freedom other than U1, it allows us to enhance the buckling capacity of the main beam without interfering with the axial compression of the main beam.
