Friction PendulumTM bearings use the characteristics of a pendulum to lengthen the natural period of the isolated structure so as to avoid the strongest earthquake forces. During an earthquake, the supported structure moves with small pendulum motions. Since earthquake induced displacements occur primarily in the bearings, lateral loads and shaking movements transmitted to the structure are greatly reduced.   Download Product Brochure   Click here to learn about the Principles of Friction Pendulum Seismic Isolation   Triple PendulumTM Bearing Single Pendulum Bearing Tension Capable Bearing Incorporates three pendulums in one bearing, each with properties selected to optimize the structure’s response for different earthquake strengths and frequencies. The original Friction PendulumTM bearing. Consists of a single slider moving on a concave surface. Can accommodate structure vertical loads that vary from compression to tension during seismic movements.
