The Design of Jianshe Bridge
Jianshe bridge is the first self-anchored cable-stayed suspension bridge in the world, localed in Dalian, China. Cable-stayed suspension was presented in history, however cable-stayed bridge and self-anchored suspension combine to make a new type system, which is economy and fit for large span bridge. This paper presents the design of Jianshe bridge. The static and dynamic character of the system and the fatigue of suspender are presented. The computing model of this new system is also introduced in the paper. The structure internal force nonlinearity and stress of the bridge are analyzed. Then analyse the calculate results and draw the conclusions, which self-anchored cable-stayed suspension bridge is fit for large-span bridge, cross suspender can reduce stress amplitude and overcome fatigue problem, and Wind-resistant stability of self-anchored cable-stayed suspension bridge is better than earth anchored system.
