Description

Technical Field

[0001] The invention belongs to the field of building structure vibration control, and in particular relates to a multi-stage energy dissipation device for building structure nodes. Background Art

[0002] Earthquake disasters are sudden and destructive, and seriously threaten the safety of human life and property. Nearly a thousand destructive earthquakes occur in the world every year. A major earthquake can cause economic losses of hundreds of billions of dollars and lead to the death or serious disability of hundreds of thousands of people. my country is located in the two most active seismic belts in the world and is one of the countries most seriously affected by earthquake disasters. The casualties caused by earthquakes rank first in the world, and the economic losses are also very huge. The massive destruction and collapse of buildings in earthquakes are the direct causes of earthquake disasters. When an earthquake occurs, the ground vibration causes the seismic response of the structure. For building structures with foundations fixed to the ground, the response is amplified layer by layer from bottom to top along the height. Due to the excessive seismic response (acceleration, velocity or displacement) of a certain part of the structure, the main load-bearing structure is severely damaged or even collapsed; or although the main structure is not damaged, the building finishes, decoration or other non-structural accessories are damaged, resulting in serious losses; or the damage of expensive indoor instruments and equipment leads to serious losses or secondary disasters. In order to avoid the occurrence of the above disasters, people must control the seismic response of the structural system and eliminate the "amplifier" effect of the structural system. The structural energy dissipation and vibration reduction technology is to design some non-load-bearing components of the structure (such as shear walls, connectors, etc.) into energy dissipation rods, or install energy dissipation devices in certain parts of the structure (interlayer space, nodes, joints, etc.). In the case of small winds or small earthquakes, these energy dissipation rods (or energy dissipation devices) and the structure itself have sufficient lateral stiffness to meet the use requirements, and the structure is in an elastic state; when a large earthquake or strong wind occurs, as the lateral deformation of the structure increases, the energy dissipation components or energy dissipation devices start to work first, produce large damping, consume a large amount of seismic or wind vibration energy input to the structure, and convert the kinetic energy or elastic potential energy of the structure into heat energy and other forms of dissipation, quickly attenuate the seismic or wind vibration response of the structure (displacement, velocity, acceleration, etc.), so that the main structure avoids obvious inelastic state, and protects the main structure and components from damage in strong earthquakes or strong winds. Because the external energy transmitted to the building structure by earthquakes and other reasons is the source of structural vibration, setting up energy dissipation devices in the structure and increasing energy dissipation will reduce the vibration response of the structure. The restrained concrete of the buckling-resistant energy-absorbing components currently under research and development is easily crushed and loses its restraint and buckling-resistant function, resulting in a significant reduction in its energy dissipation capacity. Therefore, the manufacturing process and energy dissipation performance of some energy-absorbing components still need to be further improved. Summary of the invention

[0003] In order to solve the above-mentioned technical problems, the present invention provides a multi-stage energy dissipation device for building structure nodes, which adopts multiple right-angle node shock-absorbing combination systems, is composed of a sliding shear support plate inserted into a rail sleeve connecting plate, and a primary energy-absorbing connecting nail is arranged between the two for fixed connection. When vibration occurs, the arranged primary energy-absorbing ribs and the primary energy-absorbing connecting nails will perform primary energy dissipation to buffer and resist the vibration. When the vibration forces the sliding shear support plate and the rail sleeve connecting plate to move relative to each other and reaches the limit shear force of the primary energy-absorbing connecting nail, the primary energy-absorbing connecting nail will be damaged, and the sliding shear support plate will move on the vibration sliding track to cooperate with the first connecting plate and the second connecting plate to extrude and consume energy on the elastic extrusion material. At the same time, the secondary energy-absorbing elliptical holes and the secondary energy-absorbing ribs on the multiple sliding shear support plates will fully consume energy again to achieve the secondary energy-absorbing effect. The whole device is installed at the right-angle node of the building structure, which can make the node have a certain initial stiffness and at the same time make the node have a certain seismic performance and have a multi-level shock-absorbing and energy-absorbing effect, which not only ensures that the node has sufficient stiffness, but also changes the characteristics of poor seismic resistance and energy-absorbing capacity of the right-angle node of the traditional building structure.
