Topic: Modeling Shear-Friction Along RC Cold Joint
I am attempting to model the resistance and displacement of an experimental wall structure which experiences significant slip along a cold joint (foundation-to-wall interface). I am currently using ATENA 2D, v.18.104.22.168, I was looking at using the 2-D Interface material model, and was wondering how to implement it. Can it be assigned to a line between two marco-elements, which represent the interface? Also, is there a suggested way to calculate the Ktt and Knn values, e.g. using the concrete stiffness?
Thanks for the help, please let me know if you need more information.
