Description: 

Friction Pendulum Bearings is one type of base isolation system. The superstructure is isolated from the foundation using specially designed concave surfaces and bearings to allow sway under its own natural period during the seismic events. 

Friction Pendulum Bearings have been used for a variety of structures for buildings, bridges and other structures to reduce damages caused by an earthquake. The bearings are custom designed and manufactured for each structure depending on a variety of factors.

Features：

•  Vertical load: 1000kN-60000kN 

•  Excellent horizontal deformation to absorb shock energy effectively

•  θ（rad）：θ≥0.02rad 

•  friction coefficient: μ=0.03

Types: 

• According to the design drawing of customer

Design and fabrication standard:

• GB/T 17955-2009 - Spherical bearing for bridges

• In reference with EN1337-7 - Spherical and cylindrical PTFE bearing

• In reference with 15129:2009 - Anti-seismic devices
