Horizontal force dispersed rubber bearings have the following main uses:
1. Bridge engineering field
Dispersed horizontal force: Under the action of horizontal forces such as earthquakes and wind loads, the horizontal force can be dispersed to various parts of the rubber pads and supports, avoiding the concentration of force in one place, effectively protecting the bridge structure, especially for large-span, high pier bridges and curved bridges, which can significantly improve the stability and safety of the bridge, make each pier work together, and reduce the horizontal force borne by a single pier.
Adapting to beam deformation: It has good ability to adapt to the free expansion and rotation of the beam, and can meet the requirements of large shear displacement under temperature changes, earthquakes, etc. The overall integrity of the support is good, which can effectively reduce the additional stress and risk of damage to the bridge structure caused by beam expansion and rotation.
2. In the field of architectural structures
Seismic isolation: It can be installed on the foundation or key parts of buildings. When an earthquake occurs, it absorbs and dissipates seismic energy, reduces the impact of seismic forces on buildings, lowers the vibration response of buildings, protects the main structure of buildings from damage, reduces casualties and property losses caused by earthquake disasters, and is suitable for high-rise buildings, large commercial buildings, hospitals, schools and other densely populated and important buildings.
Wind resistant stability: Under strong winds, it helps buildings disperse and withstand horizontal winds, maintain building stability, and prevent excessive displacement, shaking, or even collapse due to wind loads. It is particularly important for high-rise buildings and large-span spatial structures such as TV towers and exhibition halls.
3. Other engineering fields
Subway Tunnel Engineering: In the construction and operation of subway tunnels, horizontal force dispersing rubber bearings can be used to connect and support the tunnel structure and the ground, dispersing and absorbing the horizontal forces generated during subway operation, such as vibration and impact forces during train travel, protecting the safety and stability of the tunnel structure, and reducing deformation and cracking of the tunnel lining.
Dam engineering: For some large dams, especially in earthquake prone areas, horizontal force dispersing rubber bearings can be installed between the dam body and foundation or in key parts of the dam body, playing a role in dispersing horizontal forces such as seismic force and water pressure, enhancing the seismic performance and anti sliding stability of the dam, and ensuring the safe operation of the dam.
