Book excerpt: Fiber Reinforced Polymer (FRP) composite materials provide effective and potentially economic solution for rehabilitating and upgrading the existing reinforced and precast concrete bridge structures that have suffered deterioration. Each year, there are a significant number of damaged bridges, mainly due to reinforcing steel corrosion, structural failure or vehicle collision. Using FRP materials has many advantages over other strengthening methods. This study consists of reviewing relevant guidelines, codes, standard practices and manufacturer's specifications that deals with FRP strengthening of damaged concrete bridges based on both U.S and international sources. Based on literature review, the available design guidelines are summarized and compared. Comparison includes flexural load carrying capacity of prestressed girder and failure mode based on reviewed code provisions for an experimental model and results validated with finite element analysis. Design code recommendations are made based on the comparative study.
