The Friction Pendulum System (FPS) offers a simple approach for increasing a structure's earthquake resistance. The approach uses steel connections which absorb earthquake vibrations using small amplitude pendulum motions. The FPS connections can permit the building frames to resist severe seismic forces on an elastic strength basis, with only minimal impact on the construction cost. This paper discusses the design approach, FPS performance, an example design, and design details.
