| Abstract: | With the large-scale construction of bridge in China, the double-deck truss bridge is increasing gradually. The design and application of straight-line steel truss structure has been more mature, and the research of curved truss structure is less. Relying on Zhucheng Square Bridge in Renmin Avenue of Guiyang City, the reasonable structure layout of small-radius curved truss bridge is studied. The overall structural stress is analyzed through MIDAS CIVIL. The stress performance of key joints is studied by ANSYS so as to provide the reliable theoretical and technical support for the design and construction of small-radius curved double-deck truss bridge. |

| Keywords: | small radius curve double-deck truss bridge overall stress key joint |
