Structural Behaviors Of Beipang-jiang Suspended Steel Truss Bridge

The paper aims to conduct some research into the structure characteristics of the pre-stressed concrete oblique-pulling truss bridge with structural simulation analysis technique based on the North-pan River Bridge across Zhensheng highway in Guizhou Province. The North-pan River Bridge is a steel trussed girder suspended highway bridge, with the main span of 636 meters; the steel trussed girder is made up of the steel truss and deck hitch, in currently novel kingpost structural style.The paper analyzes the mechanical characteristics of the trussed suspended bridge in the round and obtains the variation law of displacement and inner force by establishing the space simulation model; the structural style of integral deck hitch is adopted to preferably solve the linkage between the deck hitch and truss by calculating and analyzing; meanwhile it analyzes the dynamic natures in detail, such as self-oscillation, wind resistance, quake-proof and so on; finally it studies the job practice on stiff girder. The conclusion of this paper can be a reference beneficially to the design, construct and monitor of the same-typed bridges.
