Abstract: Using CFT structure into arch rib of arch bridge is rational since CFT is resistant to the axial compressive force. In Japan, the first CFT arch bridge-the Second Saikai Bridge-is under the erection. In the meantime, the seismic safety of civil engineering structures is severely required. Therefore, the seismic safety of CFT arch bridges against strong earthquakes must be grasped. In this paper,the Jianghan Wuqiao Bridges,which is a CFT bridge in China and has the same span with the Second Saikai Bridge, is made to be the analysis object and the differences of natural vibration properties between these two bridges are discussed. Furthermore, the nonlinear seismic response properties of the Jianghan Wuquiao Bridge are discussed.
