| Abstract: | With the development of bridge design technique and construction methods,the span capacity of cable-stayed bridge can reach over 1 000 meters.The selection of structural system has been an important problem.Through the example of a 730 m-span cable-stayed bridge,different structure systems are introduced and compared,meanwhile the analysis process and results are discussed. |
