Study on Seismic Performance of Continuous Girder Bridge With Concrete Filled Steel Tubular Laced Column Piers
In recent years, the application of high pier bridges with concrete-filled steel tubular laced columns have gradually increased, especially in the western mountainous regions of China.The Ganhaizi Bridge in Sichuan Province is taken as the engineering background, then a three-dimensional finite element analysis model of continuous girder bridge with CFST laced column high piers is built with universal program of Midas Civil, aimed to research the seismic performance of this new bridge structure.Based on the time history analysis of the bridge under E1 seismic dynamic, the self-vibration characteristics and the internal force distribution of the analytical model are discussed.Moreover, the seismic design control section of the pier beam bending moment, axial force and displacement are proposed, which can put forward a research basis for the seismic design of continuous girder bridge with CFST laced column high piers, and also provide reference for the seismic design regulations of CFST composite structures.
