Compressive Strength of HPC Column with Non–Metallic Reinforcement

Abstract

Non–metallic reinforcement is of recent origin to eliminate the corrosion problems in concrete structures and is having very good qualities, which are required to tailor the need of anti corrosive reinforcement. Glass Fibre Reinforced Polymer (GFRP) rebars comes under this category and its structural properties makes it to use for variety of applications. Hence, an attempt is made to find the suitability of GFRP rebar as reinforcement for compression members. This paper aims to investigate the possibilities of identifying suitable alternate reinforcement to steel and compare their performance in terms of load carrying capacity. M60 grade of concrete was chosen for the study and the cross section of the compression member chosen is square. The slenderness ratios of 6 and 8 were adopted and the end conditions are pinned. A critical analysis is made with experimental investigations. It is concluded that the load carrying capacity of GFRP reinforced column is 56% and 40% more compared to steel reinforced column for slenderness ratios of 6 and 8 respectively.
