Abstract:By introducing and using the basic principles of the  Japanese equivalent linear method, a simplified seismic isolation design method was summarized combined with the basic requirements for seismic isolation design in the Code for Seismic Design of Buildings (GB 50010—2010). A school building with basic isolation technology was taken as an example, and the Japanese equivalent linear method and the simplified seismic isolation design method were used to design the isolation layer, and the nonlinear time-history analysis was conducted. The results show that the simplified seismic isolation design method has a clear isolation mechanism and reliable calculation results, which can be used for base isolation design.

Keywords:base isolation technology; equivalent stiffness; equivalent damping ratio; horizontal damping coefficient; Japanese equivalent linear method
