Research and Application of Anisotropic Friction Pendulum Isolation Bearing

Based on the method of performance design for bridge to reduce vibration isolation, and combined with the principle of friction pendulum isolation bearing, anisotropic friction pendulum isolation bearings is developed, the basic characteristics of which were that, isolation parameters such as stiffness, displacement and friction energy dissipation design which is gained different performance requirements is applied. And compared with the traditional friction pendulum bearing, anisotropic friction pendulum isolation Bearing is more save material and cost. A test is performed. Result shows that the thought and design of anisotropic friction pendulum isolation bearing is suitable and reasonable. Engineering application process is shown by a long span continuous beam.
