A Research of Aseismic Performance of Xushahe Bridge,a Leaning-type Reinforced Concrete Arch Bridge

The structure of Xushahe Bridge is introduced briefly in this paper considering five conditions,element setting up,calculation constant,the treatment methods to steel pipe and concrete,shearing deformation,and the quality the rigidity of bridge deck simplified to the crossbeam by means of finite element modeling.The dynamic characteristic of Xushahe Bridge is calculated considering structure initial stress and no considering the point by using finite element software.And with the analyses and calculations of the bridge earthquake response of Probability 1 and Probability 2 by using response spectrum theory,the aseismic performance of the bridge structure is discussed.The results show that 1) initial stress doesn't influence its mechanical performance largely;2) the bridge structure can resist 9.0-earthquake intensity well.
