摘　　要：以某黄河大桥为例,介绍了基于摩擦摆式支座的波形钢腹板PC刚构-连续组合梁桥的抗震特性。同时,分析对比了采用摩擦摆式支座和普通支座在动力特性、力学性能和位移响应的区别,得出采用摩擦摆式支座具有较优的抗震性能,为同类型桥梁抗震设计提供了借鉴和参考。Taking a bridge of Yellow River as an example, the seismic characteristics of the PC rigid-frame continuous composite girder bridge with corrugated steel webs based on friction pendulum support are introduced. At the same time, the differences in the dynamic characteristics, mechanical properties and displacement responses of the fiction pendulum support and ordinary support are analyzed and compared. It is concluded that the friction pendulum support has the better seismic performances,which provides a reference for the seismic design of the similar bridges.
