ABSTRACT
Investigations published on the behavior of Fiber-Reinforced Polymer (FRP)-confined concrete columns in axial compression have been generally based on specimens with small scales. In this paper, the axial behavior of carbon FRP (CFRP)-Confined Reinforced Concrete (RC) square columns with four sizes is focused, aiming to clarify the influence of size on the behavior of different scale specimens. The experimental results show that there are threshold values for the size effect on the axial compressive strength and stress-strain relationship of the columns, beyond which there are no size effects.
