This paper presents the experimental results of precast concrete columns strengthened and repaired with externally bonded carbon fiber reinforced polymer (CFRP) and grass fiber reinforced polymer (GFRP) laminates. The aims of the study were to investigate the structural behaviors of a precast concrete column with a notch and the efficiency of CFRP and GFRP laminates in strengthening and repairing the columns subjected to eccentric load. A total of 15 precast concrete columns with notches were tested up to failure. Load was applied on a column notch causing eccentric load on a column. The specimens were equally divided into five groups based on the types of fiber reinforced polymers and damage conditions of columns (undamaged or partially damaged): columns with non-strengthening/repairing; columns with CFRP strengthening; columns with GFRP strengthening; columns with CFRP repair; columns with GFRP repair. The results were compared and discussed in terms of load carrying capacity, lateral deflection, and mode of failure. It was concluded that the application of CFRP and GFRP laminates in strengthening and repairing precast concrete columns improved the load carrying capacities up to 27.6%.
