Using a stiff frame, reinforced concrete column specimens were subjected to high axial forces and cyclic reverse-curvature moments. A companion paper describing the emergency retrofit technology for improving the column load carrying capacity is to be presented by the Japanese collaborators in the 14WCEE. This paper presents the retrofit techniques for rectangular RC columns using three retrofit schemes. The objectives of this study include: (1) validating existing retrofit schemes using steel jacketing and CFRP wrapping (2) evaluating the CFRP retrofit schemes using the CFRP anchors conveniently made by hands, and (3) analyzing the responses of the tested specimens. Experimental results demonstrated that the seismic performance of the stated rectangular RC columns can be significantly enhanced by properly-constructed octagonal steel jacket. Comparing with the one retrofitted by CFRP wrapping only, the cyclic load carrying performance of the specimen was significantly improved by using the CFRP wrapping and the proposed CFRP anchors.
