| Abstract: | This article firstly introduces the main structure sizes of a 96m steel pipe-encased concrete bow string arch bridge.Then the author adopted a numerical method to analyze the deformation and stress of the bridge.The analysis result shows that the bridge takes the advantages of small height in structure,lager vertical stiffness,and better dynamic characteristics.So this type of steel pipe-encased concrete bow string arch bridge can be used widely in the future. |
