Good question

Mohsen Salari

I used "Area Spring" for defining gap where foundation is modeled by shell element. It is easy and you must select the shell, then in Assign menu select "Area Spring" and then select the "Compression Only" in that menu. furthermore you need to make all combination load nonlinear.

Ephrem Beyene

Mohsen Salari thanks a lot!

António Fonseca

Mohsen Salari you saved my day with that detail of the "non-linear" combination

Jose Roberto Rasi

I agree with Dr. Mohsen Salari,
