RETROFITTING OF RCC BEAMS USING GLASS FIBER SHEET AND JUTE FIBER SHEET

Retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion etc. Many of the existing reinforced concrete structures throughout the world are in urgent need of rehabilitation, repair or reconstruction because of deterioration due to various factors like corrosion, lack of detailing, failure of bonding between beam-column joints etc. Glass Fiber Polymer composite has been accepted in the construction industry as a promising substitute for repairing and in increment length strength of RCC structures. This paper presents an experimental study on reinforced concrete beams retrofitted with glass fiber polymer sheet and jute fiber sheet externally. The objective of this study is to investigate the behavior of beams after retrofitting using natural and synthetic fibers. Beam specimen of size 1000×150×150mm was casted. An attempt has been made to study the flexural behaviour.
