In the study of earthquake-resisting theory of building structures, the complicated question of structure energy dissipation considering soil-structure dynamic interaction is of great importance. In order to complete and promote the theory of earthquake-resisting and vibration control of building structures, and understand the mechanism of the interaction among soil, superstructure and energy dissipation devices, and develop the calculation method of the structure system response under earthquake, and guide the design of energy dissipation devices, the experimental and numerical simulation on this question should be properly carried out. The mechanism research about the effect on passive energy dissipation devices caused by soil-structure interaction will be conducted. The shaking table model test on the system of soil, superstructure and the passive energy dissipation devices will be conducted. Through numerical simulation analysis and the soil parameter identification on the shaking table model test, the analysis model of soil-structure-energy dissipation devices system will be developed, the mechanism and law of the effect caused by soil-structure interaction on the efficiency of energy dissipation devices will be studied. The three dimensional nonlinear mechanics model of soil-structure-energy dissipation devices system, computer simulation analysis method and optimization design method will be proposed to direct engineering practice.
