A Study of Seismic Performance for Guanhe Cable-Stayed Bridge

At present,it is difficult to carry out the seismic design of a cable-stayed bridge,for there is no seismic design specification to abide by.The example of the Guanhe Cable-Stayed Bridge is taken in this paper,the seismic performance analysis is introduced,including choice of seismic design criterion,modeling of the bridge,dynamic characteristic analysis,seismic input motions,seismic response analysis,seismic performance check and approach to seismic measures,moreover.The long period issue of the seismic input motion is discussed.
