Abstract | A new type of prefabricated fibre reinforced polymer (FRP) composite jacket with an innovative joining system consisting of two interlocking edges and a locking has been developed for effective repair of damaged reinforced concrete (RC) columns. In this paper, the results of the experimental investigation on the evaluation of the effectiveness of this novel prefabricated FRP jacket in repairing RC columns with different levels of corrosion damage are presented. Full scale RC columns with 25% and 50% simulated steel corrosion damage and repaired with the novel FRP repair system was tested under concentric compressive load. The corrosion in the steel reinforcement was simulated by discontinuing the longitudinal bars in the middle part of the column and replacing with non-structural PVC pipes. The stiffness and strength capacity of these repaired columns was compared with damaged and undamaged columns. The results showed that the provision of the FRP jacket fully restored the axial stiffness and up to 99% and 95% of the axial strength capacity of columns with 25% and 50% corrosion damage, respectively. Theoretical analysis was also developed to predict the axial load capacity of the repaired columns considering the partial confinement provided of prefabricated composite jackets. |
