Description

technical field [0001] The invention relates to the field of civil engineering, and relates to a support capable of realizing shock absorption and isolation of buildings, especially a support capable of simultaneously realizing horizontal and vertical shock absorption and isolation, in particular to a compact three-dimensional friction pendulum shock isolation support. Background technique [0002] At present, the seismic isolation bearings realized in engineering applications are mainly used to reduce horizontal vibrations, and those that can simultaneously reduce vertical vibrations are rare in practical applications. In addition, due to the vertical vibration caused by rail traffic, ordinary seismic isolation bearings cannot be isolated, 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 concepts and structures of three-dimensional isolation bearings, which can reduce ...
