Connection between Plates : Internal Forces

Hello everyone, 

Hope you're doing well. 

I have a diaphragm wall composed of many plates in Plaxis3D. I'm looking for a way to avoid transmission of internal forces from one plate to another. Is there a way to control the connection at the intersections ? 

(knowing that this wall will be anchored to another behind, will it help if a create a tiny spacing between the plates ?) 

Thank you !
