Abstract: Concrete filled steel tube(CFT) structures are a rational design choice for the arch ribs of an arch bridge since CFT is resistant to axial compressive forces. However, there are few experiments on the seismic properties of CFT arch bridges. Therefore, this paper introduces the vibration experiment of a CFT arch specimen in China and states the seismic performance of this arch. An analysis of the natural vibrations and nonlinear seismic vibrations on this CFT arch is carried out by using a three-dimensiional FE model. By comparing the results obtained by the analysis with those obtained by the experiment, the dynamical properties and the nonlinear seismic characteristics are discussed in detail. From results, it is confirmed that the CFT arch specimen has a good seismic performance.
