Product Application
The application scope of seismic isolation and vibration mitigation products is extremely extensive, covering a diverse range of fields including buildings and bridges. Here is a detailed as follow:
Building industry
Residential Buildings
In high-rise residential complexes situated in earthquake-prone regions, the utilization of products like seismic isolation rubber bearings and friction pendulum seismic isolation bearings can remarkably diminish the damage inflicted on buildings during earthquakes, safeguarding the lives and property of residents. For instance, numerous high-rise residential buildings in Japan have incorporated seismic isolation technology.
01
Commercial Buildings
For commercial edifices with a high density of occupants, such as large shopping malls and office towers, the employment of seismic isolation and vibration mitigation products can enhance the seismic resistance of the structures and ensure the safe evacuation of people in the event of an earthquake. Take the Taipei 101 Tower as an example, where a sizable tuned mass damper(TMD) has been installed at its base, effectively mitigating the swaying under the influence of strong winds and earthquakes.
02
Public Buildings
Public facilities such as hospitals, schools, and museums demand a higher level of structural safety and stability. The application of seismic isolation and vibration absorption products can guarantee the continued normal operation of these buildings after an earthquake, providing support for earthquake relief efforts and medical treatment. The National Stadium in Côte d'Ivoire, which was aided by the Chinese government, has utilized the seismic isolation and vibration reduction products of Hebei Luze .
03
Industrial Buildings
In industrial plants where production continuity is of utmost importance, such as electronic chip manufacturing workshops and chemical production facilities, seismic isolation and vibration reduction products can curtail the impact of earthquakes on production equipment and minimize the risk of production shutdowns caused by earthquakes.

Bridge Domain
1. Urban Traffic Bridges:
In urban viaducts, bridges spanning rivers, and other traffic bridges, the use of products like seismic isolation bearings and dampers can augment the seismic resistance of the bridges, reduce the structural damage caused by earthquakes, and ensure the smooth operation of urban traffic. For example, certain sections of the viaduct at Haikou Meilan International Airport have adopted seismic isolation bearings.
2. Railway Bridges:
The safety of railway bridges is of critical significance. The application of seismic isolation and vibration reduction products can ensure the stability of railway bridges during earthquakes and guarantee the safe passage of trains. Some high-speed railway bridges also employ seismic isolation technology during their construction.
Special Structure Realm
1
For long-span spatial structures such as convention and exhibition centers and stadiums, the use of seismic isolation and vibration reduction products can effectively attenuate the structural vibrations during earthquakes, enhancing the safety and comfort of the structures. The Northeast Asia International Convention-Exhibition Center, for example, has adopted seismic isolation technology.
2
Tall structures like TV towers and chimneys are prone to damage during earthquakes. The implementation of seismic isolation and vibration reduction products such as viscous dampers(VFD/FVD) can boost the damping of the structures, reduce the vibration responses, and improve the seismic resistance.
3
For essential lifeline project facilities such as water supply, power supply, and communication systems, the application of seismic isolation and vibration reduction products can ensure their normal operation after an earthquake and mitigate the impact of earthquakes on society.
Other Areas
1. Subway and Rail Transit
Subway stations and track structures are also at risk during earthquakes. Seismic isolation technology can be applied for vibration isolation and noise reduction of subway tracks and seismic protection of station structures, enhancing the seismic safety of the rail transit system.
2. Offshore Platforms
In the marine environment, offshore platforms are susceptible to multiple natural disasters including sea waves and earthquakes. Seismic isolation and vibration reduction products can be used to lessen the damage to offshore platforms caused by earthquakes and improve their stability and safety.
