Mai, A. Duc., Sheikh, M. Neaz. & Hadi, M. N. S. (2019). Performance evaluation of intermittently CFRP wrapped square and circularised square reinforced concrete columns under different loading conditions. Structure and Infrastructure Engineering: maintenance, management, life-cycle design and performance, 15 (5), 696-710.


This paper presents the results of an experimental investigation on square and circularised square rein-forced concrete (RC) columns intermittently wrapped with carbon fibre reinforced polymer (CFRP)under different loading conditions. Twelve RC specimens consisting of eight square RC specimenswith 150mm150mm cross-section and 800mm height and four circularised square RC specimenswith 212mm diameter and 800 mm height were tested under concentric axial load, eccentric axialload and four-point flexural load. The test results showed that intermittent wrapping increased thestrength and ductility of square RC specimens. The test results also showed that circularisation com-bined with intermittent wrapping significantly improved the strength and ductility of square RC speci-mens. The experimental axial load-bending moment interaction diagram showed that the bestperformance was achieved by intermittently CFRP wrapped circularised square RC specimens.
