Abstract :

Rehabilitation and strengthening of old structures using advanced materials is a contemporary research in the field of Structural Engineering. Over the past decades, much research has been carried out on shear and flexural strengthening of concrete beams using different types of fiber reinforced polymers and adhesives. Strengthening of old structures is necessary to obtain an expected life span. Such a method of strengthening of old structures by the help of new technology is termed as ' retrofitting '. Life span of Concrete structures may be reduced due to many reasons, such as deterioration of concrete and development of surface cracks due to ingress of chemical agents, abrasion and cavitation in hydraulic structures caused by fast moving water, improper design and unexpected external lateral loads such as wind or seismic forces acting on a structure, while are also the reason for failure of structural members. High tensile strength of specific fibers like glass fibers, carbon fibers etc. found it's application in increasing the strength of new Concrete structures as well as strengthening of older and worn out structures.
