Use of rebars in compression has not been fully habitual. Many problems are threatening the durability of the material such as corrosion and subsequent loss of strength affecting the performance of steel reinforcement. To overcome this problem, novel materials such as Fibre Reinforced Polymer (FRP) rebars have been invented. FRP bars have higher strength to weight ratio than its steel counterparts and are non-corrosive. In this study, the performance of longitudinally reinforced Glass FRP (GFRP) bars in short columns of dimensions 200 mm × 150 mm × 800 mm subjected to eccentric loading has been carried out. The longitudinal reinforcement ratio varied from 1.51% to 2.26% by keeping constant the transverse reinforcement (steel stirrups) ratio. The short columns were subjected to a load at an eccentricity of 100 mm. Effect of replacement of steel rebars and increase in longitudinal reinforcement ratio is studied in terms of maximum deflection and maximum compressive load. From the experimental results, it is observed that the increase in longitudinal reinforcement ratio of GFRP reinforced column resulted in 4.5% higher load carrying capacity and 2.2% greater horizontal deflection compared to steel reinforced column.
