The effect of a rubber sheet on the dynamic response of a machine foundation located over a small thickness of soil layer

Placing a machine footing over a small thickness of soil layer, which is located over a bedrock, could encounter many challenges due to the bed’s notable stiffness in comparison to the soil. The advantages of using rubbers to protect facilities (structures, machine foundations, nea...
