The paper presents the results of analysis of the soil-structure interaction effects considering the local site effects. The influences of the local site effects – masses, stiffness and thickness of the layered subsoil - can significantly modify the stresses and deflections of the structural system. Two important characteristics that distinguish the dynamic soil-structure interaction system from other general dynamic structural systems are the unbounded nature and the plastic strains of the soil medium. Generally, the influence of the layered subsoil will be considered to define of the seismic loads and the stiffness and damping of the complex system soil-base-structure behaviour.
