External confinement of concrete columns by means of carbon fiber reinforced polymer (CFRP) wraps have proven to be an efficient technique for structural retrofitting and strengthening. This paper presents experimental investigation to assess the residual compressive strength of CFRP wrapped 1/6-scale concrete columns using strips to enhance confinement while still enabling visual column inspection. The experimental work is carried out to evaluate the remaining strength and stress-strain behavior of partially damaged concrete columns externally retrofitted with CFRP strips. Twelve (12) cylinder specimens are constructed, instrumented and tested in three groups, including fully wrapped, partially wrapped, and unwrapped concrete column specimens with a 4 in. diameter and height of 16 in. The same concrete mix and curing conditions are used throughout the study to achieve a 4000 psi compressive strength in 28-days. All test specimens are subjected to monotonic uniaxial compression loads in two steps: (1) before retrofitting and loading up to 70% of failure point, and (2) after retrofitting and loading up to failure. Several parameters that influence confinement effectiveness of CFRP and increase the residual compressive strength of retrofitted column ware evaluated including various confinement ratios, the number of CFRP composite layers (single and double layers), and fiber orientations include 0° and 90°, with respect to the circumferential direction. The correlations between the residual strength and confinement effectiveness are presented, and different failure mechanisms are identified. Ductility is also evaluated and experimentally determined for all test specimens to determine the seismic performance of confined concrete columns. The optimum CFRP partially wrap configuration will be identified in which the maximum residual compressive strength for the retrofitted concrete columns is obtained.
