Topic: Wall Foundation Contact in Rocking Walls.
I am trying to model an unbonded post-tensioned rocking wall using ATENA 3d v5.
Ideally, the wall-foundation contact should be such that there is no horizontal slip. Also, there should be unrestricted gap opening at the tension side of the wall and there should be no indentation into the foundation at the compression side. I tried using 3D interface material model and with minimal tensile strength and high tangential stiffness to achieve the above mentioned goal but it is not giving me desired result. Could you please help me with this? Thank you.
