By comparing the traditional scheme and base isolation scheme, the influence of using seismic isolation technology on interfacial shear stress and natural vibration period was analyzed. The results show that using seismic isolation technology can extend the natural vibration period of the structure, reduce the earthquake response of upper structure and the damage on main structure, effectively improve the seisnuc properties, so as to meet the requirements of the code for seismic design of buildings.
