Taking a Yellow River bridge as an example, the seismic characteristics of the PC rigid frame-continuous composite girder bridge with corrugated steel webs based on friction pendulum system are introduced. The differences in dynamic characteristics, mechanical properties and displacement response of the fiction pendulum bearings and ordinary bearings are analyzed and compared, and it is concluded that the friction pendulum bearing has better seismic performance, which provides a reference for the seismic design of the same type of bridge.
