The vibration amplitude dependence of the construction elements on soil-structure interaction parameters

The soil conditions influence on vibration level of the construction elements is analyzed. It has been established that the damping of the structure vibrations is defined by energy radiation of vibrations into the basis by elastic waves for certain ratios between stiffness and inertia characteristics of the structure and the soil. The methods applied and calculation results of the vibration parameters of the soil-structure system for different kinds of constructions and soil conditions have been described. On analyse 1’ influence des conditions des terrains sur les vibrations des constructions. On presente les resultats des calculs des vibrations des pont en coditions differentes du terrain.
