Abstract：Research purposes: For the peculiar crankle coupling mechanics peculiarity of the curve bridge that the structure internal force is quite intricacy. In the paper the internal force of the curve obliquity reinforced concrete rigid frame continuous beam bridge is discussed as the Beijing South Station Liangshuihe rigid frame continuous beam medium span bridge as the engineering background.
Research conclusions: The crankle coupling and obliquity of the rigid pier made the distortion, the vertical moment are greater than the straight bridge's of the same spans. And the outboard deflection is greater than the inboard one. The support reactions of the curve bridge have a trend that the outboard support reactions are greater than the inboard ones, contrasted with the straight bridge of the same spans.
