Hello Sampat,

Thank you very much for your answer. Naturally I send the pic with my boundary conditions. I have elastic support below the plates, with different stiffnesses (the middle plate has a soft support, at the extremities the plates have a stiffer support). Furthermore I applied the dispalcement (which allow the free moving of the plates on on X and Z direction, and it is blocked on Y direction) on the faces of the top concrete plates in Y direction.

Between the concrete and steel dowel I applied a bounded contact. But I tried applying other contact types as well. But it is not working. 

Sorry for the order of the pictures. IIt is exactly the opposite of the subject in the text.

Regards, Szabi
