Friction Pendulum

Product Introduction

The Friction Pendulum Seismic Isolation Bearing is a type of seismic isolation and energy dissipation bearing based on the principle of a simple pendulum. It typically consists of an upper bearing plate, a lower bearing plate, a biconvex spherical crown liner plate, an upper curved slider plate, a lower curved slider plate, anchoring components, and other parts.

It utilizes the pendulum principle to elongate the structural period and employs frictional damping to dissipate seismic energy.

Its core principle lies in using the curved geometric characteristics of its structure to generate a "restoring force" (similar to the restoring force of a pendulum) when the spherical crown slides. This elongates the structure's natural vibration period, shifting it away from the predominant periods of earthquake ground motion, thereby reducing seismic response. Simultaneously, the friction between the spherical crown and the curved surfaces dissipates seismic energy, further reducing the structural seismic response.
