The finite strip method is used for the calculation of internal forces in transverse diaphragms of continuous curved box-girder.

In recent years, continuous prestressed concrete curved box-girder structure is widely used in the domestic and international large interchange project.

Dynamic analyses and experiment studies on the prestressed concrete continuous curved box-girders;

Influence of eccentric support on internal forces of 30° curved box-girder bridges with two spans;

In this paper,the problem of reaction and torsion of PC curved box-girder bridges was discussed with the space FEM(finite element method) which was used to construct the simulated model,Considering this structure and the factors such as temperature,vehicles etc.

Temperature gradient of RC continuous curved box girder bridge;

Dynamic Bayes-CG estimation of displacement parameters of curved box girder bridge based on FCS theory;

The prestress steel cable’s linetype of curved box girder bridge is three dimensional curve,which makes curved girder bridge’s force-bearing capability more complicated.

Due to the influence of the radius of curvature, the mechanical characeristic of the curved box girder bridges differ to those of the straight bridges.

On the asisit of large-scale FEM software MIDAS/ CIVIL and grillage theory, this paper builded up the model of continous curved box girder project, Ramp F of the Intercharge of Niulangguan Bridge, analyzed and discussed the result, for the reference of this kind of bridge design.
