Design And Analysis Of Isolation Seismic Of Kindergarten In Tanchang County

With the increasing speed of urbanization in China,the increasing social property,earthquake and other natural disasters will be more and more serious harm.The traditional seismic structure is through the "hard resistance" approach to resist the earthquake.This way can not effectively protect the building structure under the action of the earthquake.Anti-isolation control technology came into being.According to the idea of effective shock absorption,economy and maintenance,the design of the system is based on the design of the seismic control technology.The purpose of energy dissipation is achieved by considering the possible strong earthquake.At present,the use of isolation technology is relatively mature.Isolation technology refers to the structure between the upper structure and the lower structure of the isolation bearing.When the earthquake comes,the isolation structure through the seismic support to resist the earthquake transmission to the superstructure,to achieve the purpose of shock.At present,Rubber bearings and friction swing bearing is the application of a wide range of isolation bearing.In this paper,the actual engineering case of a kindergarten located in Tanchang County is designed,and the finite element software ETABS is used to design the isolation design with rubber bearing and friction bearing.Based on the analysis of the dynamic time history under the earthquake,the interlayer shear force of each layer is proposed,and then the maximum horizontal earthquake influence coefficient after the isolation is calculated.Through the dynamic time history analysis under the rare earthquakes,Isolation of Isolated Layer and Shear Force of Isolated Bearing.The results show that the effect of energy dissipation is obvious,and the structure can be reduced once.The structure of rubber bearing and friction pendulum is compared and analyzed,and the isolation effect is very good.
