Structural Characteristic And Mechanics Capability Analysis Of Single Diagonal-span Arch Bridge

Based on project of Red Star Ocean World View's third bridge,in the article,general layout of Single Diagonal-span Arch bridge and stability analysis of the bridge under different stiffness ratio of girder and arch,and stress analysis of anchor structure are studied.The main contents as follows:(1) Discuss on general layout of Single Diagonal-span Arch bridge.Given different distribution of cable,the effect of long-span arch bridge can be compared.The stiffness ratio of girder and arch directly affects the stress distribution of the whole bridge,keep balance of amount of the steel both girder and arch,change the ratio of stiffness between both two, observe the change of the structure,find the change law.The length of non-stayed cable segment of two ends of girder greatly affects the stress of the whole structure,though trial calculation find the suitable length of the Single Diagonal-span Arch bridge.(2) Analysis of anchor structure of girder and arch.The anchor structure of cable-girder and cable-arch are the key structure during the design of long-span steel arch bridge.Make use of large scale universal analysis software ANSYS build calculation model consisted of plate elements,make out Von-Mise stress picture,compare the stress of kinds of plates.(3) Make use of large scale universal analysis software ANSYS do linear elastic and elastic-plastic stability analysis on different stiffness ratio of girder and arch.
