ABSTRACT
Repair and strengthening of R.C beam is now becoming more and more important in the field of
structural strengthening and retrofitting. The present paper reviews the study of Glass Fiber
Reinforced Polymer (GFRP) flats under flexural behavior in reinforced concrete beams. In this study,
experimental investigation on the flexural behavior of RC Beam has been studied by wrapping Glass
Fiber Reinforced Polymer (GFRP) sheets. Reinforced Concrete Beam externally bonded with GFRP
sheets were tested to failure using a symmetrical two point static loading system. Six Reinforced
Concrete Beams have been cast for this experimental test. All cast beams are weak in flexural and
having same reinforcement detailing. Three beams are used as control beams and three beams are
strengthened using full bottom of glass fiber reinforced polymer (GFRP) sheets. The experimental
result shows, that full bottom GFRP sheet wrapping in 70% preloaded beam can increase flexural
capacity of the beam by 14%(on ultimate load) as compared to Controlled Beams.
Key words: Glass Fibre Reinforced Polymer, Concrete Beams, Flexural Strengthening, Deflection.

1. INTRODUCTION
1.1. GENERAL
Reinforced cement concrete is an extremely popular construction material used for structural components of
a building like beams, columns and slabs etc. One major flaw of RCC is its susceptibility to environmental
attack. This can severely decrease the strength and life of the structures. The repair of structurally deteriorated
RC Structures become necessary since the structural element ceases to provide satisfactory strength and
serviceability. Some of these structures are in such a bad condition that they need to be replaced. Two
