ansys workbench shell+beam

[nicnoc]

Hello, everyone. I imported from catia a structure constituted by a reticulate of steel beams (line body) on which lie steel panels (shell). shell+line body should behave as if they were perfectly bound. I created a part in the design modeler. but when I carry out the analysis the behaviour of the elements is totally disjoined.
how do I bind them correctly?

Maybe with a model we can clarify this... see you
