Abstract: Base-isolation technique has been considered is one of the effective ways to resist earthquakes. The design and analysis of based isolation of a frame construction were introduced. The basic theory of isolation technology and the bearings and dampers isolation device were discribed. The different model of base isolation and dynamic analysis methods were summarized, the basic principle and important parameters of seismic isolation design were introduced. According to the three and isolation design related standards of research, comparative analysis of them in the range of application and others of the difference and connection were done. The base isolation technology was applied to the engineering example, adopting the finite element analysis software for comparative analysis of the original frame structure and the isolation structure in earthquake.

Keywords: frame construction; base isolation; isolation design; isolation bearing
