Under what circumstances should pot bearings be used instead of elastomeric bearings?
1、Elastomeric
Elastomeric is a type of support that utilizes the characteristics of elastic deformation to provide shock absorption, isolation, and load-bearing functions in structures. It usually consists of upper and lower panels, clamps, elastic pads, and fixed iron plates.
elastomeric bearings can be classified into various types based on the material and hardness of their elastic pads. For example, common ones include rubber bearings, polyurethane bearings, etc. The differences in their materials and hardness also affect their applicability and load-bearing capacity.
The advantage of elastomeric is that they have good seismic isolation performance, which can effectively reduce the strong impact and vibration caused by earthquakes. In addition, the installation and maintenance of elastomeric bearings are relatively simple.
2、 Pot bearings
Pot bearings is a commonly used prestressed concrete structural support, which is usually composed of a lower basin seat, an upper steel plate, isolation pads, etc. Pot bearings usually undertake functions such as load-bearing, displacement, and rotation in structures.
The advantage of pot bearingss is that they have high load-bearing capacity and stability. In addition, pot bearings have a longer service life and better corrosion resistance. However, the disadvantage of pot bearings is that the isolation effect varies depending on the material of the isolation pad.
3、 The difference between elastomeric and pot bearings
From a structural perspective, the main difference between elastomeric and pot bearings lies in their constituent components. Elastomeric are mainly composed of elastic pads, clamps, fixed iron plates, and other components, with rubber, polyurethane, and other elastic materials as the main materials. The pot bearings is composed of pot base, steel plate, isolation pad and other components, and the material is mainly reinforced concrete.
From the perspective of application scenarios, elastomeric are suitable for situations that require seismic isolation, shock absorption, and other functions, and are suitable for construction, bridges, and other engineering projects. Basin type bearings are suitable for situations that require load-bearing, displacement, and rotation, and are suitable for construction projects such as highways and bridges.
In general, elastomeric and pot bearings are very commonly used types of bearings, but suitable bearing types need to be selected in different projects and occasions to ensure the stability and safety of the structure.
Conclusion
This article provides a detailed introduction to the differences between elastomeric and pot bearings, analyzing their components and application scenarios. I hope it can be helpful for readers when choosing and applying support types.
