In last decades, the use of externally fiber-reinforced polymer sheets (FRPs) has become increasingly popular for civil infrastructure applications. Early investigate studies have demonstrates that confinement enhancement of FRP wrapped circular columns is more efficient than that of square or rectangular RC columns. Most existing columns however, are square or rectangular in cross section. An experimental study has been carried out on rectangular RC columns strengthened with carbon fiber- reinforced polymer (CFRP) sheets. A total of 9 RC columns were loaded to failure in axial compression and examined in both axial and lateral directions. Number of wrap layers and aspect ratios were the main test parameters. Compression stress, axial and transverse strain have been registered to estimate the stress-strain relationships, ultimate strength and ductility of specimens. Results obviously indicate that CFRP wrapping can improve the structural performance of rectangular RC columns regarding both maximum strength and ductility. The effects of test parameters are evidenced and compared
