Friction Pendulum Seismic Isolation Bearing

China [CN] Friction Pendulum Seismic Isolation Bearings are advanced structural components designed to reduce seismic impact on buildings and infrastructure by utilizing the pendulum effect and controlled friction. These bearings consist of a combination of spherical sliding surfaces, friction plates, guide devices, and damping assemblies that work together to convert earthquake-induced kinetic energy into heat through friction, while also allowing controlled horizontal displacement and vertical load transfer. Their structural design includes upper and lower bearing plates, stainless steel sliding interfaces, rubber sealing rings, and a spherical pendulum mechanism that extends the natural vibration period of a structure, thereby reducing acceleration and enhancing seismic protection. Available in fixed (GD), one-way sliding (DX), and multi-directional sliding (SX) types, Friction Pendulum Bearings accommodate various movement demands and structural layouts. Key advantages include automatic re-centering, reliable performance across different load conditions, and minimal influence from environmental factors. These bearings are widely applied in bridges, high-rise buildings, hospitals, museums, and other critical facilities in seismic zones, ensuring long-term durability, energy dissipation, and structural resilience during earthquakes.
