Matsenko A. Soil-Structure Interaction at dynamic and seismic effects.

The thesis is devoted to analysis of influencing of dynamic Soil-Structure Interaction (SSI) on dynamic responses of the system «building - foundation - soil» (BFS). The dynamic interaction of a building with the ground basis is considered from a position of the registration of dynamic responses of a ground defined on the basis of the requirements of existing standards, and on the basis of that constructing dynamic models of buildings for dynamic and seismic designs. The researches of dynamic responses of rigid massive Nuclear Power Plant's buildings and changing estimation of seismic loads on buildings stipulated by interaction of the foundations with the ground basis are held. The influencing of interaction is connected to the ground basis on dynamic responses of buildings and seismic loads on them with a diversity of constructions, ground conditions and with a different relation of their rigidities. The experimental researches envisioned obtaining experimental values of parameters of a natural oscil lation of inspected buildings both buildings and their basis. For the registration of the elastic basis and the masses of the foundation are obtained respective transitional and associated matrixes. Designed in the present operation the technique of definition of dynamic responses and seismic loads at the system BFS is included in standards of seismic designing buildings of Ukraine. Keywords: soil-structure interaction, dynamic system, experimental data of oscillations, building, foundation, base, standard guideline.
