Please explain, what is the rinter value in PLAXIS 2D? how can this determine for particular structure?
Dear Cristina,
I recommend reading paragraph 6.1.7.2 of the PLAXIS 2D 2023 Reference Manual.
With kind regards,
Dennis Waterman
Dear Stefanos
Could you please explain why do we reduce the strength and stiffness of the interface??

Dear Shaija,
I would strongly advise you to check our Manuals, Reference and Tutorials to better understand about Rinter.
In short, this is a generic factor to reduce both the strength and the stiffness of the interfaces. This value should not be a parameter for which the design can drastically change. This is a rough way of reducting strength and stiffness. This depends on the materials you have. In principle concrete with clay material has a completely different relative behaviour compared to sand or granular material.
If changes in the Rinter highly affect the analyses you perform you should choose to create a dedicated material for the interface behaviour and switch the option to Custom as shown below. Then you can directly provide the properties of the interface:
