the important application of this composite retrofitting technology is the use of fiber reinforced epoxy composite laminates (FRECL) or sheets to provide external confinement to RC columns when the capacity of existing structure is inadequate.Use of externally bonded FRECL composite for strengthening can be a cost effective alternative for upgrading the performance of existing RC columns. More research work is been carried out analyzing on the flexural behaviour of RC beams, efficiency of HFRECL confinement related to the radius of the cross-section edges, size and shape of the concrete column cross section. The aim of this paper is to study the structural behavior of reinforced concrete columns strengthened with carbon fiber laminates and glass fiber laminates and compare their results with unretrofitted columns. The main task of this eperiment were conducted to investigate the effects of additional strengthening of reinforced columns. Composite materials have been subject of permanent interest of various specialists during the last decades Composites offer many advantages when compared to metal alloys, especially where high strength and stiffness to weigh ratio is concerned, excellent fatigue properties and corrosion resistance.
