Approximately 40% of Canadian bridges currently in service were constructed forty to fifty years ago. Many existing structures suffer from structural integrity problems, such as corrosion, and require significant repairs. In some cases, complete replacement of the structure is necessary. Fibre reinforced polymers (FRPs) have shown great potential as a structural material due to its high strength, resistance to corrosion, light weight and ease of construction. Hybrid FRP-concrete structural members have become of particular interest. This paper will investigate the different applications of hybrid FRP-concrete structural members and the experimental research studies performed on these members in Europe and Asia. Summaries of results from experimental tests and analytical investigations are provided with a focus on the effect of factors such as the type of shear bond used at the FRP-concrete interface and FRP fabrication methods on the ultimate load resistance and failure mode.
