I'm not familiar with those warnings.   Include images that show the warnings exactly as they appear in the LS-DYNA output (d3hsp or mes*).

You can create a part set with all three beam parts and put that part set as SURFA of one *CONTACT_AUTOMATIC_GENERAL.

If are just concerned only about 1 dof, I'd probably use a spring element defined with *ELEMENT_DISCRETE and *SECTION_DISCRETE.  For the material, use *MAT_SPRING_ELASTOPLASTIC or *MAT_SPRING_NONLINEAR_ELASTIC, depending on what sort of nonlinear behavior you want.
