Metal buffer damper is a kind of energy dissipation, shock absorption device, with superior energy dissipation performance, simple structure, convenient manufacturing, low cost, easy to replace. It can be used as an energy consumption unit or a limiter in conjunction with isolation mounts and isolation systems. So, let's take a look at the main characteristics of metal buffer dampers.

Main features of metal buffer damper:

1. Small yield displacement, small displacement can start energy consumption;

2. Large limit displacement. Different from the mild steel shear damper, which is affected by the properties of mild steel, the ultimate displacement of the damper can be infinite according to the need in theory.

3. The hysteresis curve is close to rectangular, very full, and the energy consumption effect of the damper is very obvious.

Metal buffer damper is usually made of low-stress steel, which is a kind of energy dissipation damping device in the passive control of structure. In the event of earthquake and wind vibration, the soft steel will have plastic yield hysteresis deformation, thereby dissipating the energy input in the structure and achieving the purpose of shock absorption. Mild steel has excellent low cycle fatigue and hysteretic properties. Including torsion beam, bending beam, U-shaped steel and other forms.

Vibration characteristics of metal buffered dampers

The metal buffer damper provides additional stiffness and damping for the structure, and uses the good hysteretic properties of mild steel to dissipate the input seismic energy to protect the main structure. Compared with the traditional seismic system, the metal buffer damper has the advantages of better damping effect, simple technology, stable and reliable, and wide applicability. It will become a kind of energy absorbing system widely used in practical engineering.

The scope of application is not limited by the height and layout of the building, which can be used for wind resistance and seismic control of new buildings, and can also be used for traditional strengthening and maintenance of buildings, and has a good application prospect.

Metal buffer damper can avoid or reduce the post-earthquake recovery work, significantly reduce the damage of large earthquakes to the structure, and effectively the seismic response of the structure.

How to build safe buildings and structures in sudden strong earthquakes and adopt safe, effective, reasonable and economic structure system is an important subject in the engineering field, which has important practical significance and far-reaching historical significance for effectively alleviating earthquake disasters.

People have accumulated rich experience in the process of resisting earthquake disaster for a long time, and the seismic isolation technology has been changed from the traditional and passive seismic method to the active and active seismic isolation method. The use of shock isolators and metal buffer dampers to extend the vibration period of the property, increase the damping ratio, consume the energy released to the property by the earthquake, and reduce the attack of the seismic force on the property.

The metal buffer damper technology can reduce the seismic response of the structure on the "flexible energy dissipation" road, reduce the installation of shear walls, reduce the section and reinforcement of the structure, and improve the seismic safety.
