Slipping interface

Hi,

I am modelling a slab and I would like to define a slipping interface between a beam and the shell, in order to not transfer axial force from the slab to the beam, but only the self weight. The beam axis lays on the shell plane and connected then by all the points (see pictures below).

Do you know if there is an option in Teddy to “release” the axial force?

Thanks
