| Abstract: | Base on engineering case of small radius continuous steel box-girder curved bridge of D ramp and F ramp in an interchange, this paper introduces its structural characteristics and spatial calculation analysis method. The plane of this bridge is an irregular curve. The beam element and spatial lamina shell element modeling is sued to calculate, compare and analyze its end reaction, intensity and rigidity as a reference for the design of similar bridges. |
