Abstract:

Spliced structural members for supporting a traffic deck on a short span bridge. A spliced structural member includes a plurality of metal box-shaped girder segments placed end to end and splice channels nested around the adjacent ends of the girder segments. A spliced joint is formed by connecting the splice channels to the adjacent ends of the girder segments. The spliced joint has at least 75% of the flexural and shear strength of the girder segments and provides continuity for structural strength and rigidity for the spliced structural member.
