Through the research of the formation of the frame, it is found that the tilted frame is more stable than the ordinary one because the tilted column increased its lateral stiffness and thus its displacement and librations are decreased.

Statement of the inclined leg rigid frame bridge structure made of reinforced concrete;

The frame structure with braces is a kind of structure which has more reasonable force bearing behavior and is more economic compared with the traditional frame-shear wall structure.

In this paper,the behaviours of the transfer girder and upper(bracing) frame structures in combined action are analyzed, with a Calculation method and some design proposals concerning this kind of structure presented, which can be referred to in the design of similar structures in actural engineering.
