Modeling and Comparison of Interface Behavior Between Soil and Concrete Considering the Effects of the Soil - Structure Interaction

A simple developed thin - layer element from the interface of the soil and structure is used in a finite element process to simulate different operating modes of soil - structure dynamic interaction. The constitutive behavior of the interface is defined by splitting it into its cutting and normalized components. Nowadays, using pieces of worn-out rubber is a suitable method to strengthen the soil and increase the soil loading capacity. It is also a way to recycle rubber waste materials. With the knowledge that more behavioral compatibility with the soil and concrete interface has a better damping effect in the quake-separator, in order to simulate the behavior of the interface, soil and rubber were used with different percentages of 10, 20, 30 and 40 percent which provided acceptable results in the modeling of the intersection of soil and concrete.
