Analysis of Base-Isolation Building System

In order to improve the effect of isolation structure, the principles and behaviours of the base-isolation system are studied, and the types and characteristics of the base-isolation are also discussed. Compared to the traditional aseismatic structures, the base isolation structures decrease the seismic response obviously: the total structural aseismatic value decrease 1/4-1/32, the seismic shear stress in the upper structure decrease 1/14-1/23. In the huge seism, the structure can have the obvious aseismatic effect.
