Description

technical field [0001] The invention belongs to the fields of civil engineering, mechanical engineering and seismic isolation technology, in particular to a three-dimensional seismic isolation and anti-sway device and method with self-balancing. Background technique [0002] my country is a major country in the world, and its geographical location is between the two major seismic belts of the Pacific Rim and the Asia-Europe seismic belt. Almost all regions have experienced destructive earthquakes of magnitude 6 or above. The disasters and consequences of earthquakes are very serious. Therefore, in order to eliminate and weaken the huge threat to people's life and property caused by earthquakes, it is very important to design a seismic isolation device that is safe, reliable, easy to use, easy to maintain, and low cost. At present, the research and development of horizontal isolation technology is relatively mature. In recent years, many scholars and experts have carried out ...

AI Technical Summary

Problems solved by technology

Due to the relatively greater vertical stiffness of the structure, it is difficult for ordinary shock-absorbing measures (such as various dampers) to play an effective role

At the same time, when an earthquake strikes, as each support point of the building moves up and down, the structure will sway irresistibly, which will cause the building to sway. The damage of such swaying to the building will become more serious as the building height increases. It can be seen that it is necessary to develop a three-dimensional isolation device that can simultaneously achieve horizontal and vertical isolation and suppress structural sway
