ABSTRACT

At present, in domestic seismic isolation buildings, seismic isolation bearings are usually set on the top of the foundation. At the same time, the domestic seismic isolation technology related regulations only have clear provisions for basic seismic isolation buildings. In this paper, for the construction project where the seismic isolation support is located on the top of the basement, using the CSI ETABS 2013 Nonlinear C tool, the seismic isolation model establishment, seismic isolation calculation and analysis are carried out. The research in this paper shows that the use of suitable isolation supports, reasonable isolation analysis models and seismic waves, as well as correct isolation calculation and analysis methods can reduce the inter-story shear and inter-story displacement of the upper isolation layer building project ; The seismic response of the structure above the isolation layer can be reduced by 1.5 degrees, and the seismic measures can be reduced by 1 degree; it can reduce the seismic response of the upper isolation layer construction project, and effectively improve the seismic performance of the structure above the isolation layer.
