Seismic Response of the Large Span Prestressed Concrete Continuous Girder Bridge

YU Qian-hua1,XIA Pei-hua1,SONG Ze-gang2,ZHANG Kai2(1.School of Civil Engineering & Architecture,Changsha University of Science & Technology,Hunan Changsha 410076,China;2.Institute of Yunnan Highway Science & Technology,Yunnan Kunming 650051,China)  
In general,large span of continuous prestressed concrete girder bridges only place one fixed buttress.For the bridge span is longer,the vertical seismic response of a fixed pier is also correspondingly larger.Using response spectrum,the impact of the seismic response of different types of bearings bound for a fixed bridge pier and fixed bearing is discussed.The results show that different types of restraint bearing have a greater impact on the seismic response of continuous bridge.At the same time,the impact of pile-soil interaction on continuous bridge dynamic characteristics and the seismic response is also analyzed.The results of this research can provide references for the anti-seismic design of similar bridges.
