Background Art

[0002] The seismic isolation bearings currently used in engineering applications are mainly used to reduce horizontal vibrations, and those that can simultaneously reduce vertical vibrations are rare in actual applications. In addition, due to the vertical vibrations caused by rail transit, etc., ordinary seismic isolation bearings cannot isolate them, which will affect the comfort of the building and even the normal use of some buildings. Many designers at home and abroad have also proposed a variety of three-dimensional seismic isolation bearing concepts and structures that can reduce the vertical vibrations caused by earthquakes and the vertical vibrations caused by vehicles, mechanical equipment, etc. However, many current design schemes have large structural dimensions and no vertical energy-consuming units, high costs, and low practicality, so there are relatively few cases of actual application.
