Friction Pendulum-Type Seismic Isolation Ball Bearings


Description

The friction pendulum-type seismic isolation spherical bearing is a modern seismic isolation device characterized by its simple structure, reliable performance, and maintenance-free design. Its period, vertical load capacity, damping ratio, lateral displacement, and tensile strength can all be individually controlled. Under the influence of strong earthquakes, this friction pendulum isolation system can reduce the seismic forces transmitted to the structure by 3 to 5 times. The key to its advanced technology lies in the precise customization of the friction coefficient between the patented sliding material MSM and its counter-material, ensuring efficient, quantifiable energy dissipation as well as reliable structural reset capabilities. This has resulted in a range of proprietary technologies that span from the structural level down to the material composition itself.

 

Performance Features

As a seismic isolation device representing modern vibration-control technology, it features a simple overview, easy calculations, and reliable construction—making it a highly mature technology. Moreover, through structural optimization, it does not increase the overall project cost.
