Abstract
<p>Fibre-reinforced polymer (FRP} bars can be a promising sustainable alternative to steel due to their low life-cycle cost and potentially low environmental impact as a reinforcement. Also due to their corrosion resistance and electromagnetic neutrality, they have attracted significant interest for use in reinforced concrete (RC} structures. This paper investigates the behaviour of FRP-reinforced concrete (FRP-RC} columns with varying slenderness ratios. The reduction in moment capacity, axial load capacity and load-moment interaction diagrams of FRP-RC columns with the increase in slenderness are studied in comparison to steel-reinforced concrete (steel-RC} columns. The study shows that guidelines and design standards such as Eurocode 2 for steel-RC pertaining to the simplified design of slender columns, slenderness limit and minimum reinforcement ratio need to be revised for FRP-RC columns.</p>
