What is an isolation bearing

What is a seismic isolation bearing?

Seismic isolation bearings refer to load-bearing components used for the contact between building load-bearing structures and foundations. Their main function is to reduce the seismic sensation of buildings when subjected to vibrations. This type of component usually consists of two parts: an internal elastic element and an external protective layer, which can serve to isolate or reduce vibration.

Application scenarios of seismic isolation bearings

Seismic isolation bearings can be applied in many engineering fields, mainly including the following aspects:

1. High rise buildings

Seismic isolation bearings are widely used in high-rise buildings, which can reduce the damage of external vibrations such as earthquakes to buildings. For example, the use of seismic isolation bearings in some high-rise buildings can reduce the internal seismic sensation by about 70% during earthquakes, which plays a very important role in protecting the building.

2. Bridges

In bridge engineering, seismic isolation bearings also play an important role. Due to the frequent passage of vehicles and pedestrians, the structural stability of bridges is crucial. Isolation bearings can reduce the impact of vibration on bridges and protect the integrity and stability of bridge structures.

3. Pipeline

In pipeline engineering, seismic isolation bearings can be used to protect the stability and safety of pipelines, reducing damage caused by external vibrations during transportation, crossing geological areas, and other processes.

Advantages of seismic isolation bearings

Compared to traditional bearing structures, seismic isolation bearings have several obvious advantages:

1. Improve the safety of buildings

Isolation bearings can protect the integrity and stability of buildings to a certain extent, reduce damage from external factors such as earthquakes, and improve the safety of buildings.

2. Reduce vibration sensation

Vibration sensation is a very obvious feeling that people have during earthquakes or other external vibrations. Isolation bearings can effectively reduce the vibration sensation of buildings when they are subjected to earthquakes or other external vibrations, and improve people’s sense of safety.

3. Reduce engineering costs

Isolation bearings can reduce engineering costs because they can lower the degree of damage to buildings during external vibrations such as earthquakes, and reduce maintenance and replacement costs. In addition, seismic isolation bearings can also extend the service life of buildings.

【 Conclusion 】

As a new type of building material, seismic isolation bearings have significant application value and promotion prospects. With the development of technology and the improvement of people’s safety awareness, the application of seismic isolation bearings will become increasingly widespread and play a more important role in the future construction field.
