| Abstract: | The structural behaviors of curved prestressed concrete frame bridge with high pier and long- span are investigated in this paper. The influences of the curve of girder in plane on the deformation and stress distribution of bridge are discussed. The study may provide some suggestions for design and construction control of curved frame bridge to some extent, which may have practical meaning. |
