Background

Earthquake disasters are sudden and destructive, and seriously threaten the safety of human life and property. Destructive earthquakes occur nearly thousands of times per year in the world, and a major earthquake can cause economic losses in the billions of dollars, resulting in the death or serious disability of hundreds of thousands of people. China is in two most active earthquake zones in the world and is one of the most serious countries suffering earthquake disasters, casualties caused by earthquakes live at the first place of the world, and economic losses are very large. The great damage and collapse of buildings in the earthquake are the direct causes of earthquake disasters. When an earthquake occurs, ground vibration causes the seismic response of the structure. For building structures with a foundation fixed to the ground, the reaction is amplified layer by layer along the height from bottom to top. The main body bearing structure is seriously damaged and even collapsed due to overlarge earthquake reaction (acceleration, speed or displacement) of a certain part of the structure; or, although the main structure is not destroyed, the architectural decoration, finishing or other non-structural accessories, etc. are destroyed to cause serious loss; or damage to expensive equipment and equipment in the room can cause serious damage or secondary disasters. In order to avoid the disasters, people need to control the earthquake reaction of the structural system and eliminate the amplifier function of the structural system, and the structural energy dissipation and vibration reduction technology is to design some non-bearing components (such as shear walls, connecting pieces and the like) of the structure into energy dissipation rod pieces or install energy dissipation devices at some parts (interlayer spaces, nodes, connecting joints and the like) of the structure. In the case of small winds or small earthquakes, the energy dissipation rod pieces (or energy dissipation devices) and the structure have enough lateral rigidity to meet the use requirement, and the structure is in an elastic state; when a large earthquake or a large wind occurs, along with the increase of the lateral deformation of the structure, the energy dissipation component or the energy dissipation device starts to work first to generate large damping, so that earthquake or wind vibration energy input into the structure is greatly consumed, the energy of kinetic energy or elastic potential energy of the structure is converted into heat energy and the like to be dissipated, the earthquake or wind vibration reaction (displacement, speed, acceleration and the like) of the structure is quickly attenuated, the main body structure is prevented from generating an obvious inelastic state, and the main body structure and the component are protected from being damaged in strong earthquake or large wind. Because the external energy transmitted to the building structure due to earthquakes and the like is a source of vibration generated by the structure, the energy consumption device is arranged in the structure, so that the energy consumption is increased, and the vibration reaction of the structure is reduced. The restrained concrete of the anti-buckling energy dissipation component researched and developed at present is easy to crush and loses the restraining and anti-buckling effects, so that the energy dissipation capacity of the anti-buckling energy dissipation component is greatly reduced. Therefore, some energy consuming member manufacturing processes, energy consuming performance, and the like still need to be further improved.
