The Friction Pendulum System uses the isolation pendulum principle by adjusting the radius of curvature of the isolation period so that the weight of isolated buildings is independent of the set period. Therefore, it can easily and effectively solve light load buildings and structures where weight fluctuates such as water towersand storage tanks.

The Friction Pendulum System is composed of three parts, mainly consisting of steel. A flat top plate is in contact with the lower concave panel. A sphere that is able to slide (bearing) is between the plates. The areas that are in contact are coated with a material that has low coefficient friction,

The Friction pendulum bearing isolation system will carry the entire structure. In order to reduce the incoming seismic force, the isolated upper structure produces a smaller acceleration that reduces the seismic force greatly.

Characteristics: periodic constant; insensitive to temperature; resistant to torsion; durable.
