Aseismatic Performance Analysis Of Storey Isolation System In High-rise Frame Structure

China is on the junction of Eurasian seismic zone and circum-Pacific seismiczone, seismic activity is frequent, the earthquakes have brought great harm to people’slives, economic development and social stability, so it’s important to improve theseismic capacity and promote the development of the energy dissipation technology ofthe structure. High-rise buildings are emerging with the quick economic developmentof China and urbanization, the study of interlayer seismic is necessary and urgent.Through literature review and summarized, the article gives a detaileddescription of the generation and development of the base isolation and interlayerseismic technology in the world. Rubber bearing is very important in the isolationsystem, its performance has a great influence on the isolated effects of the building, sothere is an introduction about the different types of isolation bearings, size parameters,calculations assume, design and selection in real engineering. There are severalcalculation models of the interlayer seismic structure in the theoretical calculations,such as single-particle model and two-particle model, the article introduces theassumptions and solving steps of the different computing models, then buildsmomentum equation to calculate.Then we create non-isolated structure, base isolation structure and1-15layersinterlayer seismic structure with the connection properties of ETABS, next reasonablechoose seismic waves to conduct time-history analysis under horizontal seismic, thenwe check the period results with the SATWE’S data, at last compare the story shears,top acceleration, top floor displacement and reach the following conclusions:compared with non-isolated structure, the high-level interlayer seismic structure haslonger period and greater damping, the layer-shear and top acceleration and top floordisplacement turn smaller under the earthquake. All those prove that the high-levelinterlayer seismic structure can make an energy dissipation work and will be differentwith the change of the isolation layer, generally the location of the isolation layerhigher up, the worse the damping effect.
