摘要：Isolation technique of ground structure is a hot topic in the field of earthquake engineering and structure *** 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 *** 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 *** 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 *** 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.

摘要：SIM （semi interlocking masonry） is a kind of innovative building system for mortar-less walls. It utilizes a special method of interlocking SIM bricks that allows relative sliding of brick courses in-plane of a wall and prevents out-of-plane relative movement of bricks. It has increased capacity to dissipate earthquake energy through friction between bricks compared with traditional masonry. It can be used in earthquake resistant frame structures as infill panels, which also act as EDD （energy dissipation devices）. However, as a mortar-less system, it is not covered by masonry design standards. The purpose of this paper is to introduce S1M and also to develop an analytical design procedure for this innovative masonry system.
