Abstract:

Steel truss bridges are an efficient and aesthetic option for highway crossings. Their relatively light weight compared with plate girder systems make them a desirable alternative for both material savings and constructability. A prototype of a welded steel truss constructed with an integral concrete deck has been proposed as a potential alternative for accelerated bridge construction (ABC) projects in Montana. This system consists of a prefabricated welded steel truss topped with a concrete deck that can be cast at the fabrication facility (for ABC projects) or in the field after erection (for conventional projects). To investigate possible solutions to the fatigue limitations of certain welded member connections in these trusses, bolted connections between the diagonal tension members and the top and bottom chords of the truss were evaluated. In this research, both a conventional cast in place deck system and an accelerated bridge deck system (cast integral with the truss) were evaluated for the bolted/welded steel truss bridge. A 3D finite element model was used to more accurately calculate the distribution of lane and truck loads to the individual trusses. Truss members and connections for both construction alternatives were designed using loads from AASHTO Strength I, Fatigue I, and Service II load combinations. A comparison was made between the two truss configurations and a 205 ft. plate girder used in a previously designed bridge over the Swan River. Materials and fabrication estimates suggest the cost of the conventional and accelerated construction methods is 10% and 26% less, respectively, than the plate girders designed for the Swan River crossing.
