The acceleration,displacement and Vibration Dose Value(VDV) of the structure under two typical ground shocks in different vibration isolation systems are calculated and the comparison of isolation effects between the one layer vibration isolation system and double layer vibration isolation system is given.

Research on working mechanism of story isolation structure;

Theoretical study on story isolation system

simplified analysis on calculation model of interlayer seismic isolation;

Here the application of the interlayer seismic isolation in some engineering is introduced,and the finite element program—ETABS is used for making out the dynamic nonlinear time-history analysis.

This paper describes the working characteristic of interlayer seismic isolation.

Setting isolation layer is a new technology between superstructure and substructure of project,which can reduce earthquake damage.

For new buildings,a new type of steel -asphalt composite isolation layer can be set in the top surface of foundation,which has advantages of good damping effect,low cost and convenient construction,and is suitable for most new buildings in rural areas.

The vibration reduction mechanism and dynamic characteristics of the interlayer seismic isolation system and the difference between such system and the base isolation system are introduced.
