Abstract

Fifteen RC columns and one plain concrete column with inadequate transverse reinforcement were tested under uniaxial compression after being jacketed externally with carbon fiber reinforced polymer (CFRP) sheets. CFRP layer thickness, cross-section shapes and concrete strength were the test parameters. External confinement of columns with CFRP sheets resulted in an increase in the strength and ductility. The behavior of the CFRP jacketed columns was also predicted by the proposed stress-strain model. There was reasonable agreement between analytical behavior and experimental data.
