STRUCTURAL REHABILITATION OF AN OFF-SYSTEM BRIDGE USING EXTERNALLY BONDEND CFRP LAMINATES

This paper presents the use of Fiber Reinforced Polymers (FRP) laminates for the flexural strengthening of a concrete bridge superstructure. The system consists of Carbon Fiber Reinforced Polymers (FRP) laminates bonded onto the concrete surface in order to provide the necessary flexural reinforcement for the deck. The bridge superstructure selected for this project is a 4-span reinforced concrete (RC) slab. The bridge is located on Route 0039 in Washington County, Missouri - USA. The bridge analysis was performed for maximum loads determined in accordance to AASHTO Design specification, 17th edition. The strengthening scheme was designed in compliance with the ACI 440.2R-02 design guide.
