Abstract: In the base-isolated structure, due to the large difference between the horizontal stiffness of the isolation layer and the stiffness of the upper structure, the seismic isolation layer consumes a large amount of energy in the process of seismic action, which can effectively reduce the seismic response of the superstructure and keep the upper structure in elastic state. The base isolation structure was simplified into a two-particle model, and the critical stiffness ratio was derived based on th... More
