The present study analyzes the flexure behavior of the circular CFT member through experiment and numerical analysis. Through comparison between experimental and numerical results, whether or not the member was a full composite have little effect on the behavior. There circular CFT’s flexure behavior when considering pure moment is almost similar regardless of the interface characteristics between the steel and concrete. This is because there is no difference in the neutral axis of the full-composite and non-composite circular CFT member.
