Abstract

This study investigates experimentally and theoretically the axial stress-axial strain behavior of carbon fiber reinforced polymer (CFRP) confined square and circularized hollow concrete specimens under axial compressive loading. The parameters investigated theoretically in this study included the corner radius and the size of the hole. The results showed that increasing the corner radius increases the axial stress and axial strain capacity of CFRP confined hollow concrete specimens. Increasing the hole size reduces the confinement efficiency of CFRP confined hollow specimens.
