This paper presents the results of an experimental study on the axial compressive behavior of carbon fiber-reinforced polymer (CFRP)-confined high-strength concrete (HSC) columns with circular cross-section under eccentric compression loading. The axial loading was applied to the specimens at six different load eccentricities ranging from zero to 50 mm. The results indicate that the load eccentricity significantly affects the axial stress-strain behavior of FRP-confined HSC. An increase in the load eccentricity results in an increase in the ultimate axial strain but a decrease in the second branch slope of the axial stress-strain curve, which translates to a reduced ultimate axial stress.
