Confinement with fiber reinforced polymers of reinforced concrete columns is promising retrofit solution for improving ductility of existing structure. In the study, plastic deformation capacityof fiber reinforced polymers confined square and rectangular reinforced concrete columns were parametrically evaluated. Recently released seismic strengthening recommendations of American Concrete Institute were considered for calculating plastic rotation of specified columns. Fiber reinforced polymers confined concrete model provided by the design guideline was utilized for calculating moment curvature relationship of fiber reinforced polymers confined reinforced concrete columns. Numerous sectional analysis was performed with combination of various parameters (concrete strength, axial load ratio and number of fiber reinforced polymers plies). Plastic rotations of columns were determined with plastic part of the curvature and plastic hinge length for evaluating the effects of parameters on plastic deformation capacity.
