Abstract

The application of FRP as a strengthening material in bridges have been widely accepted in recent years. To demonstrate the effectiveness of FRP sheets in concrete bridge decks with no transverse reinforcement, a two-span simply supported reinforced concrete slab with no transverse steel reinforcement was studied through both field test and numerical analysis. The structural behavior was verified with a FEM model. An externally bonded FRP laminate system is a feasible solution to upgrading the obsolete bridge to meet the current design requirement for transverse reinforcement. The load tests indicate that the FRP strengthening of the concrete bridge meets the deflection requirement stipulated in the standards. The FEM analysis generally supports the field observations from load tests. The FRP sheets improve the integrity of the overall bridge deck to a certain degree, making two halves of the bridge deck partially work together. The parapet and curb of the solid slab bridge significantly contribute to the overall stiffness of the bridge system.
