Overview
Principles of Construction
High damping rubber bearings are isolation devices designed specifically for bridge engineering, mainly used to reduce vibration, noise, and vibration, ensuring the safety and stability of bridges.
It is made of high damping rubber material, which has unique properties and can effectively absorb and dissipate energy. Under the action of earthquakes or other dynamic loads, high damping rubber bearings can exert significant seismic isolation effects, reducing the deformation and vibration of bridge structures. In addition, high damping rubber bearings have the characteristics of high stability, easy installation, and wide applicability, which can meet the needs of various bridge engineering.
In bridge engineering, the application of high damping rubber bearings can effectively improve the seismic performance of bridges, protect bridge structures from natural disasters such as earthquakes, ensure smooth traffic and the safety of people's lives and property
Product advantages
The main advantages of high damping rubber bearings in bridge engineering include shock absorption and isolation, adaptability to deformation, strong bearing capacity, and good durability.
Firstly, high damping rubber bearings have excellent shock absorption and isolation capabilities. When an earthquake occurs, it can utilize its high damping characteristics to consume seismic energy, reduce the transmission of seismic forces to the upper structure, and thus protect the main structure of the bridge from serious damage. This type of support is like a wise and resilient warrior, capable of vertically supporting the weight of a bridge and horizontally dampening the destructive force of earthquakes.
Secondly, high damping rubber bearings have good adaptability to deformation. Bridges may deform due to temperature changes, concrete shrinkage and creep, vehicle loads, and other factors during use. High damping rubber bearings can adapt to these deformations through elastic compression, shear, and other deformations of rubber, avoiding excessive displacement between the beam and the bridge pier or abutment.
In addition, high damping rubber bearings also have extremely strong vertical bearing capacity, ensuring the stability and safety of the bridge under normal use. Its horizontal deformation ability is also excellent, which can release some horizontal seismic effects during earthquakes, effectively reducing the wind damage to the bridge.
Finally, high damping rubber bearings have good durability, excellent resistance to low cycle fatigue, thermal air aging, ozone aging, acid resistance, water resistance, and other properties. They can maintain their performance in harsh environmental conditions for a long time and provide long-lasting support for bridges.

The working principle of high damping rubber bearings is mainly to absorb and consume seismic energy through the elastic deformation and damping effect of rubber, protecting bridge structures from damage.
Specifically, when an earthquake occurs, seismic waves are transmitted to the bridge foundation, and the rubber layer in the high damping rubber bearing undergoes elastic deformation. This deformation can absorb seismic energy and reduce the direct impact of the earthquake on the bridge. Meanwhile, rubber materials have a high damping ratio, which can effectively convert earthquake energy into thermal energy and dissipate it into the surrounding environment, further reducing the damage of earthquakes to bridges. In addition, high damping rubber bearings also have a certain horizontal displacement capability, allowing the upper structure of the bridge to undergo horizontal displacement relative to the piers and abutments, avoiding damage caused by uneven stress. |

Product Structure
|
High damping rubber bearings are mainly vulcanized from high damping rubber materials and structural components such as steel plates. The design of this type of support enables it to maintain the outstanding mechanical properties of laminated rubber bearings while also having a high damping value.
Specifically, high damping rubber bearings consist of several uniformly thick rubber layers, with a reinforcing steel plate placed between adjacent layers to enhance their overall structural strength. The bottom surface of the support is usually flat, while the upper end may form installation counterholes for connection with the bridge structure. In addition, according to specific design and functional requirements, high damping rubber bearings may also include other components such as upper sealing plates and mortises to ensure stable connection and operational reliability between the bearings and the bridge structure. |

Applications
|
High damping rubber bearings are mainly used in various bridge structures in bridge engineering, such as beam bridges, arch bridges, cable-stayed bridges, suspension bridges, etc. Installing high damping rubber bearings between the bridge piers and span structures can absorb and dissipate seismic energy, reduce the impact of seismic forces on the bridge structure, protect the structural safety of the piers, and ensure that road traffic can recover as soon as possible after an earthquake. In addition, high damping rubber bearings can effectively balance the longitudinal and transverse forces caused by vehicle traffic, significantly improving the safety and durability of bridges. |
