Modern industrial construction practice requires solutions to many problems concerning machine foundations. Modern manufacturing facilities have hammers, presses and turbines according to their production machinery. Vibrations due to machines may cause damage to structures nearby or even to machines themselves. These effects may extend to the surroundings and affect laborers and other sensitive machines within same place or neighboring residential areas. The Vibration amplitude and the forces transmitted to the supporting medium can become the governing factor of the foundation of these machines. So knowledge of the dynamic behavior of the foundation is important. The energy transmitted through soil and the response of the foundation system is essential for proper design of the system. This paper analyzes the response of a rigid raft foundation rested on the soil to eccentric harmonic, periodic and impulse forces (impact load).
