Abstract:Â Due to ageing, poor maintenance, corrosion caused by poor environmental conditions, and accidental events such as earthquakes, concrete structures can deteriorate. With ever-increasing demands, the necessity to update degraded civil engineering infrastructure becomes even more pressing. As a result, restoring and retrofitting civil engineering infrastructure has been recognised as a critical problem that has to be addressed. Glass fibre is a novel material that is particularly successful in reinforcing work and is made up of tightly spaced glass and resins. The basic idea is that large strains occur in the vicinity of the reinforcement. The magnitude of the strain is determined by the distribution and subdivision of reinforcement throughout the mass of concrete. This paper investigates the strengthening of reinforced concrete columns using glass fibre laminates. The usage of Glass fibre as exterior confinement to concrete specimens is studied in this research. The efficiency of confinement is determined by comparing the behaviour of retrofitted specimens to that of ordinary specimens.
