Description

Zigzag-shaped anti-buckling energy-dissipating support

technical field

The invention relates to an energy-dissipating support of a building structure, in particular to a zigzag-shaped anti-buckling energy-dissipating support for vibration control of a building structure.

Background technique

Earthquake disasters are sudden and devastating, which seriously threaten the safety of human life and property. Nearly a thousand destructive earthquakes occur every year in the world, and a major earthquake can cause hundreds of billions of dollars in economic losses, resulting in hundreds of thousands of deaths or serious injuries. my country is located in the two most active seismic belts in the world, and is one of the countries that suffered the most serious earthquake disasters. The casualties caused by the earthquake rank first in the world, and the economic loss is also very huge. The massive destruction and collapse of buildings in earthquakes is the direct cause of earthquake disasters. When an earthquake occurs, ground vibrations cause the seismic response of the structure. For a building structure whose foundation is fixed to the ground, its response is amplified layer by layer along the height from bottom to top. Due to the excessive seismic response (acceleration, velocity or displacement) of a certain part of the structure, the main load-bearing structure is seriously damaged or even collapsed; loss; or damage to indoor expensive instruments and equipment leading to serious losses or secondary disasters. In order to avoid the occurrence of the above-mentioned disasters, people must control the seismic response of the structural system and eliminate the "amplifier" effect of the structural system.

Structural energy dissipation and vibration reduction technology is to design some non-load-bearing members of the structure (such as supports, shear walls, connectors, etc.) etc.) Install energy dissipation devices. When there is a small wind or a small earthquake, these energy-dissipating rods (or energy-dissipating devices) and the structure itself have sufficient lateral stiffness to meet the use requirements, and the structure is in an elastic state; As the deformation increases, the energy-dissipating components or energy-dissipating devices start to work first, producing greater damping, consuming a large amount of earthquake or wind vibration energy input into the structure, and converting the kinetic energy or elastic potential energy of the structure into thermal energy and dissipating it. , quickly attenuate the seismic or wind-induced response (displacement, velocity, acceleration, etc.) of the structure, so that the main structure can avoid obvious inelastic state, and protect the main structure and components from damage in strong earthquakes or strong winds. Because the external energy transmitted to the building structure due to earthquakes and other reasons is the root cause of the structure's vibration, so installing energy-consuming devices in the structure to increase energy consumption will reduce the vibration response of the structure. Various energy-dissipating supports can be formed by using energy-dissipating components in supports, such as cross supports, diagonal supports, K-shaped supports, etc.

The anti-buckling energy-dissipating support currently researched and developed has Chinese Patent No. 200710062637.3, which discloses an invention patent named "Steel Tube Anti-Buckling Energy-Dissipating Support"; ; Chinese Patent No. 200910081817.5 discloses an invention patent titled "An all-steel structure anti-buckling energy-dissipating support"; Invention patents, etc. However, the restrained concrete of some anti-buckling energy-dissipating braces is easily crushed and loses its restraint and anti-buckling functions, resulting in a significant reduction in its energy dissipation capacity. Therefore, some energy-dissipating support manufacturing processes, energy-dissipating performance, etc. still need to be further improved.
