The curved box-girders of Hefei Xinqiao International Airport Terminal were taken as a background of this article. Aiming at the type of the cross section, thickness of the steel plates and curvature of the beam axis, parametric analysis was carried out to evaluate the ultimate bearing capacity of this kind of curved box-girder. Using the finite element analysis software ANSYS, the effects of former three parameters was calculated. From the results, it could be found out that the ultimate bearing capacity increases as the section aspect ratio grows, and it increases linearly as the thickness of the flange and web plate grows. In addition, the ultimate bearing capacity increased and decreased with the increment of the curvature of the beam axis R. The finite element results provided a theoretical basis for experimental research and analysis of the local models provided reasonable suggestions for design as well.
