Seismic isolation from the structural point of view of technology development, seismic isolation bearing is the application of more mature seismic forms. In this paper, starting with the working principle of the seismically isolated bearing, this paper briefly introduces the characteristics of the pendulum bearing. Through the influence of the parameters of the anti-vibration pendulum bearing on the seismic performance in recent years and the influence of the input parameters of the dynamic vibration and the dynamic characteristics of the bridge on the anti-seismic performance of the anti-vibration pendulum bearing, The research progress of reducing earthquake in bridge engineering are discussed respectively. Finally, according to the research status of friction pendulum bearing in bridge engineering, the related problems and research directions of friction pendulum isolation device in the field of bridge isolation technology are discussed.
