Description
technical field [0001] The present application relates to the fields of civil engineering and mechanical engineering, and in particular, to an adaptive variable stiffness three-dimensional seismic isolation device. Background technique [0002] At present, basic isolation technology is regarded as one of the most important technological advances in the field of earthquake engineering in the 20th century, and has been widely used in the world. The basic principle of seismic isolation technology is to set seismic isolation bearings at the bottom of the building to obtain a seismic isolation layer with low horizontal stiffness, and reduce the seismic acceleration response of the superstructure through the filtering effect. And by setting up energy-consuming devices in the seismic isolation layer to absorb and consume the energy of ground vibration. Modern seismic isolation technology has a history of recent years and belongs to a passive vibration control technology. [0003]...
