What is the purpose of a isolation bearings

Isolation bearings are mainly used in building structures to effectively absorb external forces such as earthquakes, wind loads, and traffic vibrations, protecting the overall safety of the building structure.

The purpose of seismic isolation bearings

Building isolation technology is an important component of modern structural design. Isolation bearings are a special type of support device used in the following areas:

1. In the building structure

The main function of seismic isolation bearings in building structures is to reduce the contact between the building structure and the ground. When the building is subjected to external forces such as earthquakes, they reduce the frictional and inertial forces of the building system, thereby reducing the vibration of the structure.

2. In the bridge

The application of seismic isolation bearings on bridges is to connect buildings and foundations, effectively isolate the effects of earthquakes and wind loads on bridges, and ensure the overall safety of bridges.

3. Support for equipment and machinery

On the support of machines and equipment, seismic isolation bearings are mainly used to isolate the impact of external vibrations on machines and equipment, preventing equipment breakage or failure caused by external vibrations.

Working principle of seismic isolation bearings

The main working principle of seismic isolation bearings is to reduce the contact area between the structure and the underground, thereby reducing the inertia and frictional resistance of the building system. Under the influence of external forces such as earthquakes, wind loads, and vehicle passage, seismic isolation bearings can absorb and disperse most of the energy, thereby reducing the impact of passive stress on the building system.

According to different principles and damping methods, seismic isolation bearings can be divided into various types such as traditional one-way seismic isolation bearings, two-way seismic isolation bearings, and three-dimensional seismic isolation systems. In practical applications, corresponding types of seismic isolation bearings can be selected for different occasions and needs to achieve the best seismic isolation effect.

【 Conclusion 】

Seismic isolation bearings are a common structural support device, whose main purpose is to reduce the contact between the building structure and the ground, reduce the inertia and frictional resistance of the building system, and effectively isolate the impact of external vibrations on the building. In practical applications, selecting the appropriate type of seismic isolation bearings plays an important role in ensuring the overall safety of building structures.
