According to statistics, 41% of my country's land area and more than 50% of cities are located in areas with an earthquake intensity above 7 degrees. Earthquakes above 7 degrees in mainland my country account for about 10% of the world's continental earthquakes. The death toll caused by the earthquake accounts for about 1/3 of the global earthquake death toll. my country is facing a very severe form of earthquake disaster. the

my country's building structure seismic code requires that building structures and their components must have sufficient seismic load capacity and resistance to deformation. The earthquake resistance of traditional building structures depends on the resistance of the structure itself. The foundation is embedded in the soil of the foundation, and the seismic response is gradually amplified from the base to the top. However, in order to improve the bearing capacity of the structure, the cross-sectional area of the components must be increased. This method Not only lead to heavy structure but also very consumable materials, in addition, the cost of existing building shock-absorbing and shock-isolating devices is generally high, and cannot be widely used. the
