Abstract

"External application of FRP composites has been adopted for strengthening and/or repair of concrete structures in many applications during the last two decades. However, the research into shear strengthening using FRP composites has not been widely conducted as compared to flexural strengthening and axial load capacity increase, and the results obtained thus far are scarce and sometimes controversial. This study presents a review of analytical studies and design guidelines on shear strengthening of concrete structures with externally-bonded FRP laminates, and their assessment with experimental data collected from the literature. The strengths and weaknesses of each model and design guidelines/codes/specifications are identified and evaluated in order to understand the behavior of the concrete structures strengthened in shear with FRP systems and to propose additional research required to develop a more accurate analytical model. In addition, the predictions obtained by the analytical models and design guidelines/codes/specifications were compared to the experimental results to evaluate the accuracy. This comparative evaluation showed that none of the analytical models and design guidelines/codes/specifications was able to provide reliable estimates, which indicates that the mechanisms of FRP strengthening for shear are still poorly understood. As a result, parameters that are not taken into account in these analytical and design methodologies, but that affect the behavior of members strengthened in shear with FRP were identified"--Abstract, page iii.
