Due to the ongoing environmental changes, degradation of directly exposed material is seen very often. This results in issues related to aesthetics, function, and most importantly, the safety of the structures. Reinforced cement concrete (RCC) is the most commonly used material for construction where steel bars are used as reinforcement. Steel reinforcement in contact with the chemicals like chlorides and sulphates etc. which are very commonly present in urban and industrial areas and other aggressive environment, gets corroded, thus affecting the structural behaviour. Research studies propose replacing steel rebars with Glass Fibre Reinforced Polymer (GFRP) bars due to its non-corrosive properties. This paper presents the analysis and design of GFRP reinforced concrete columns. Present design methods mentioned in Indian Standard Code are not applicable to design GFRP reinforced RC columns directly. This study is an attempt to develop design provisions for GFRP reinforced concrete columns similar to those in practice for steel-reinforced columns. The spacing of ties influences the capacity of the column to carry load and failure type of compression member. So, this paper will also focus on the design of ties to provide proper confinement.
