This paper has treated extradosed cable-stayed bridge of Anbang River as engineering background. By adopting Midas/ Civil finite ele-ment procedure,and the natural vibration characteristics of the bridge using sub spatial repetitive process is calucated. The result can provide the reference for the health detection and maintenance of the bridge in the process of operation. And it also plays a reference role to further un-derstand the dynamic property of extradosed cable-stayed bridge.
