Overview
Principles of Construction
Building friction pendulum isolation bearing is a type of bearing that utilizes the pendulum principle to achieve seismic isolation function, and has the ability to withstand vertical loads and horizontal displacements. The bearing achieves seismic isolation by dissipating seismic energy through friction at the sliding interface, and extends the structural motion period through spherical oscillation. According to the structural form of the sliding friction surface, the building friction pendulum isolation bearings can be divided into two types: Type I is a single main sliding friction surface Type I, and Type II is a double main sliding friction surface type
Product advantages
1,Superior seismic performance: Friction pendulum isolation bearings extend the structural vibration period through spherical oscillation, and the sliding interface friction consumes seismic energy, effectively reducing the destructive effect of earthquakes on buildings and improving their seismic safety.
2,Long service life: Friction pendulum isolation bearings have high durability, mainly made of metal and stainless steel. After optimized combination, their volume and height are greatly reduced, they are lightweight, and easy to install.
3,Low maintenance cost: Although friction pendulum isolation bearings require regular maintenance, their maintenance cycle is long, which can reduce the long-term maintenance cost of buildings.
4,Easy installation and disassembly: The installation and disassembly of friction pendulum isolation bearings are relatively simple, and can be flexibly moved and adjusted according to needs.
5,Economy: Under the premise of meeting safety requirements, the cost of friction pendulum isolation bearings is relatively low, and their seismic reduction effect is significant, with high economic value.

1. Sliding friction consumes energy: Friction pendulum supports utilize the sliding between two curved surfaces to dissipate seismic energy. When an earthquake occurs, the upper and lower structures of the support interact with each other through friction, which can offset some of the seismic energy and reduce the seismic force transmitted to the upper structure.
2. The pendulum principle extends the natural vibration period: The friction pendulum support extends the natural vibration period of the structure through the pendulum principle. The support is designed in a pendulum shape, and when an earthquake occurs, the upper structure of the support swings like a pendulum, thereby extending the natural vibration period of the structure. This extension reduces the amplification effect of seismic waves, further reducing the seismic force transmitted to buildings. |

The basic components include anchoring device, upper support plate, upper sliding friction surface, spherical crown body, lower sliding friction surface, and lower support plate. The friction material of the sliding friction surface is usually made of polytetrafluoroethylene, modified polytetrafluoroethylene, or modified ultra-high molecular weight polyethylene, while the support is made of steel, and the dust-proof enclosure is usually made of EPDM rubber material |

Applications
|
Building friction pendulum isolation bearings are mainly used in areas where natural disasters such as earthquakes, winds, and waves occur frequently, as well as high-rise buildings, large bridges, nuclear power plants, public facilities, and industrial buildings.
Specifically, in earthquake prone areas such as Japan, Taiwan, New Zealand, etc., building friction pendulum isolation bearings are widely used in residential buildings, high-rise residences, and villas to provide residents with a safer living environment and reduce the risk of building damage and casualties during earthquakes. At the same time, in commercial buildings such as shopping malls, office buildings, hotels, as well as densely populated places such as schools and hospitals, seismic isolation bearings also play an important role in ensuring the safety of these places and reducing the impact of earthquakes on commercial operations and social services.
In addition, in public facilities such as museums, libraries, archives, sports venues, exhibition centers, transportation hubs, etc., building friction pendulum seismic isolation bearings are widely used to protect precious cultural relics, books, and archival materials, improve the seismic performance of large venues, and ensure the safe evacuation of personnel and the normal operation of facilities during earthquakes. In the field of industrial construction, such as factories, warehouses, and petrochemical facilities, seismic isolation bearings are used to protect industrial production equipment and material storage facilities, reduce the impact of earthquakes on industrial production and safety risks. |
