Four columns were kept square as reference, four columns were modified with round corners and wrapped with three layers of CFRP, and four were circularised by circular segments and wrapped with three layers of CFRP. Specimens from each group were tested under concentric, eccentric (15 or 25 mm) and flexural bending. Results from the study showed that segmental circular concrete covers considerably reduce stress concentration at the corners. FRP wrapped columns with circular segments showed significant increase in load-carrying capacity compared to columns with only round corners.
