Abstract
The through steel truss girder bridge can be a competitive bridge type for medium span highway bridges owing to the advantages of its low architectural height,fast construction speed and good durability.In the structural design of a through steel truss girder highway bridge,the plate-type portal frame and steel-concrete composite floor system were applied.In this paper,the design features and construction schemes of the floating-and-pulling erection of the bridge are presented.The presentations in the paper may serve as reference to the design of similar bridges.
