In this paper, the development history of CFST arch bridge carried out a systematic summary of the theoretical calculation of CFST arch , respectively, from the rigidity in , force calculation , stress calculation and checking , dynamic performance analysis and other aspects in detail, discusses Arch Bridge finite element analysis theory and dynamic analysis of the bridge structure calculation method . Hebei chenjiagou bridge engineering background , from a unit type selection, boundary conditions , load processing and other aspects elaborated Arch Bridge modeling methods, and on the geometric situation modeling process simulation, stress stiffening element , values ??of material properties and other issues were discussed. Through the establishment of chenjiagou mechanical model , the natural frequency of its calculation and dynamic response analysis and calculation .
