Abstract:
Isolation technique of ground structure is a hot topic in the field of earthquake engineering and structure dynamics. Since soil-isolated structure dynamic interaction study is of great significance to enhance seismic performance of isolated structures and revision of relevant isolation specifications, research on dynamic interaction of soil-isolated structure has attracted more and more attention. Based on the basic theory of soil-structure dynamic interaction, we summarize and analyze the research status quo of soil-isolated structure dynamic interaction by means of theoretical analysis, numerical simulation, model test, prototype observation and seismic performance. After reviewing the results of previous research, we reveal that some key issues, which can be used to uncover dynamic interaction mechanism and seismic response characteristics of soil-isolated structures interaction system, should not be neglected. Based on the concept of seismic performance design and the latest research of soil-isolated structure dynamic interaction, we predict the future development of soil-isolated structure dynamic interaction by elastoplastic time history analysis method, seismic performance level and practical analysis method based on energy.
