Abstract
Glass fibre-reinforced polymer (GFRP) rebars are preferable alternatives to steel bars for minimizing corrosion problems. In this study, experimental and analytical work are carried out to investigate the behaviour of GFRP reinforcement versus traditional steel reinforcement in self-compacting concrete columns under eccentric loads. The GFRP-reinforced columns have lower carrying capacities than the steel-reinforced columns, with a difference of ∼24%. Furthermore, the two confining materials (of the tube and spirals) improve this reduction. The analytical results show good agreement with the experimental results for steel-reinforced columns, whereas the GFRP-reinforced columns report a noteworthy contrast.
