Overview
Principles of Construction
Metal yield damper is a structural seismic (vibration) device made of special metal materials (soft steel) or alloys that is easy to yield and has high energy dissipation. It mainly utilizes the inelastic characteristics of metals after yielding to dissipate the energy input into the structure by external excitations such as earthquakes, and belongs to displacement related energy dissipation and vibration reduction devices.
Metal yield dampers have various structural forms, such as shear type and bending type, which respectively utilize the shear deformation and bending deformation of metals to dissipate energy. These dampers have the advantages of being sturdy and durable, requiring no maintenance for long-term use, and their seismic (vibration) performance is not affected by temperature. They are currently the most economically efficient products among various energy dissipation and shock absorption devices.
In addition, metal yield dampers have the characteristics of simple appearance, symmetrical and compact structure, easy installation, excellent fire resistance, and good durability. Therefore, they have been widely used in building structural systems, providing strong guarantees for structural safety
Product advantages
1. High energy consumption capacity:
Metal yield dampers can utilize the inelastic characteristics of metals after yielding to dissipate energy from external inputs such as earthquakes, effectively reducing structural vibration and deformation, and improving the seismic performance of structures.
2. Recoverability and high initial stiffness:
When subjected to excessive force, the metal yield damper will deform, but when the external force is removed, it can return to its original state and maintain stable performance. At the same time, in the initial stage, dampers have high stiffness and can withstand large loads, providing effective support for the structure.
3. Controllable yield strength:
By selecting different metal materials and manufacturing processes, the yield strength of metal yield dampers can be accurately controlled to meet the needs of different structures and provide customized solutions.
4. Small size, easy installation:
Metal yield dampers have a small volume, diverse interface methods, can be easily placed inside building walls, have minimal impact on building structures, and are easy to install.
5. Economy and practicality:
The metal yield damper is sturdy and durable, requiring no maintenance for long-term use. Its seismic performance is not affected by temperature, and it is relatively inexpensive. It is currently one of the most economically efficient products among various energy dissipation and shock absorption devices. Considering both economic and practical aspects, the practicality of shear type metal dampers is superior to that of bending type metal dampers. Currently, shear type dampers are almost dominant in the market.

The working principle of metal yield dampers mainly utilizes the plastic deformation characteristics of metal materials to absorb and dissipate energy generated by external excitations such as earthquakes and winds. When external stimuli (such as earthquakes) act on the structure, the metal material in the damper will yield and absorb and dissipate this energy through plastic deformation. This energy dissipation mechanism can effectively reduce the vibration amplitude of the structure under external excitation, thereby improving the seismic performance of the structure. Specifically, metal yield dampers (such as shear dampers) generate displacement through structural deformation, causing the plate to yield and undergo inelastic deformation, thereby dissipating energy |

Applications
|
Metal yield dampers are mainly used in key positions of building structures to improve their seismic resistance and safety. Specifically, its application scenarios include but are not limited to:
High rise buildings: Metal yield dampers are often installed in high-rise buildings to enhance their seismic performance and reduce the impact of earthquakes and wind vibrations on the building.
Bridge structure: In bridge engineering, metal yield dampers also play an important role in absorbing and dissipating energy generated by seismic or wind loads, protecting the safety of bridge structures.
Important facilities, such as power facilities, oil platforms, and other critical infrastructure, often use metal yield dampers to enhance their seismic resistance and ensure stable operation under extreme conditions.
Earthquake prevention: In areas with frequent earthquakes, metal yield dampers are widely used in various types of buildings to minimize losses and casualties caused by earthquakes.
In addition, metal yield dampers can also be applied to other structures that require improved seismic performance, such as transverse support frames, suspended equipment structures, etc |
