Abstract: Concrete Filled Steel Tubular (CFT) arch bridges are excellent in strength under in-plane load. However, they are not always excellent in seismic safety under out-of plane seismic load. A partial CFT arch bridge may be useful to improve seismic safety. In this paper, the dynamic properties of the partial CFT arch bridge are discussed by using the existing partial CFT arch bridge built in China (Sanqian Bridge). Firstly, the validity of analytical model is examined by ambient vibration test of this bridge and vibration experiment using moving vehicle. Then,by changing the concrete filled length,the effect of the filled length on the natural frequencies and earthquake response is discussed.
