The friction-slip seismic isolation technology has the advantages of cost economy,simple design,etc.,and is widely used in various types of seismic isolation buildings.Based on the principle of friction-slip vibration isolation,combined with the characteristics of the existing masonry structure,a new type of friction-slip device is designed and applied to the existing structural reinforcement design.Combining engineering examples,three sets of multi-layer masonry structure models with different connection methods are established to compare the acceleration,base shear and displacement responses of different connection forms of the foundation under rare earthquakes.The test results show that the installation of the friction-slip seismic isolation device can greatly reduce the seismic response of the structure.Setting the limit type friction slip connection can also have a good shock isolation effect.The increase of the limit device can effectively reduce the bottom slippage and meet the requirements of engineering use.According to engineering examples,the specific structure of the"double foundation ring beam"device for friction-slip seismic isolation,as well as the plane layout in the reinforcement design and the structure of key parts are explained,which is the application of friction-slip technology in the reinforcement design.Provide ideas with further optimization.
