Extradosed cable-stayed bridge is a new bridge structure in the world,with large span capacity,good economics and beautiful appearance. With a practical project of extradosed cable-stayed bridge as an example,the finite element software MIDAS / CIVIL is used to establish the finite element modeling of the bridge and the dynamic property of extradosed cable-stayed bridge is analyzed,then the natural vibration frequency and vibration mode of the bridge are obtained. The study can provide references for the aseismic design for extradosed cable-stayed bridge.
