石家庄铁道学院毕业设计The Design of Shot-span Suspension BridgeAbstractThe subject of this thesis is the design of a suspension bridge, which the arrangement is 13m+68m+13m. The deck system is made of steel and the tower is composed concrete. Suspension brides with a long history are developing rapidly recently. In the family of bridge, the suspension bridges are widely applied in practical. For their merit of light distinguished capability of span, and aesthetic shape. It is the very best kind bridge to across wide rive, strait and gulf.The subject is performed in according with the basic theory of suspension bridge dynamic and stationary analysis theory. The span, main cables tower and anchorages are designed in line with the arrangement of span. The way choose the parameters and decisive elements are illustrated. Thereafter, the sizes of deck system, main cables, end link, cable bands, storm system and anchorages are designed.As a highly redundant system, it is inevitably brings us much difficult in the analysis of the internal forces by hand. The computer program, which named Ansys are used in course of calculation in order to simply the work. When the internal stress is carried out, the arrangement of internal stress is implemented in light of bridge specification. After checking the items required in the code for the across-sections, we can know the feasibility of the design.Key word: Suspension bridge Deck system Main cables Pylons Anchorages
