External confinement by the wrapping of CFRP jacketing provides an effective method for the seismic retrofit on reinforced concrete members. Research results over the path year proved evidence that RC columns with square cross-sections retrofitted using CFRP wrapping or jacketing was not effective for ductility due to the brittle breakage on square corner zone and the bulging on the column face at the plastic hinge location. Therefore, this study proposes a new technique of CFRP wrapping combined with CFRP anchors. In this experimental study, a total of six full-scale specimens were tested by cyclic lateral force and constant axial loadings. Test results indicated that comparing to test conducted on the specimen wrapping CFRP alone, the anchoring technique significantly improved the column behaviors of confinements on rectangular columns and increase the ductility as well as the ability of energy dissipations. Based on the test results, the new technique is applicable for design recommendations.
