Strengthening of Reinforced Concrete Structures With Near Surface Mounted FRP Rods

The overall objective of this research project was to investigate the effectiveness of NSM FRP rods as a strengthening system for RC structures. First, bond characterization of NSM rods was carried out on coupon-size specimens, varying type of FRP rebars, bonded length and groove size. Then, the structural performance of full-size simply supported RC beams externally strengthened with NSM FRP rods was investigated. Glass and Carbon FRP rods of different sizes were used for flexural strengthening. Performance of the tested beams and modes of failure are presented in this paper. The test results confirm that NSM FRP rods can be used to significantly increase the flexural capacity of RC elements.
