Abstract:
The design, construction, and monitoring of a bridge with fiber-reinforcedpolymer (FRP) and glued laminated (glulam) girders with FRP tensionreinforcing and a composite concrete deck, constructed during fall 2003in Fairfield, Maine, are addressed. The use of a composite concrete deckwas motivated by the fact that deflection often governs the design of glu-lam girder bridges, and composite behavior increases the stiffness of thebridge by over 200% and significantly increases strength. The structurerelies on a dowel-type shear connector to ensure composite action betweenthe girders and the concrete deck. The design and construction of thisbridge required the laboratory testing of both the shear connectors andgirder specimens to determine their fatigue durability and strength as wellas the development of new analysis tools. An overview of the laboratorytesting program is given, including the fatigue testing of both the dowel-type shear connectors and two 9.15-m-span FRP–glulam–concrete beams.Strains and displacements measured during the testing program agreewell with the analysis results. Design details of the 21.3-m-long bridge inFairfield are discussed, followed by a summary and assessment of the con-struction of the bridge. Strains and displacements measured during liveload testing of the bridge are reported, which indicate that the as-builtbridge achieves a high degree of composite action.
