Paper Details

The aim of this research was to check the possibility of using Fiber-Reinforced Polymer (FRP) material forretrofitting of T-shape reinforced concrete (RC) non-pre-stressed Bridge girders. From last few decades, the use ofinnovative composite materials such as Fiber Reinforced Polymer (FRP) for strengthening, upgrading and rehabilitationof existing reinforced concrete structures. It is use because of their superior qualities such as light weight, easy to apply,high strength to weight ratio, and show efficient performance in strengthening and up gradation of reinforced concretestructure. Non-pre-stressed reinforced concrete (RC) T–shape bridge girder model was casted which dimensions were ¼of the prototype bridge girder dimensions. After casting the girder they were tested and damage it to their ultimatestrength. Girder model was failed only in flexural and flexural cracks developed only at four feet central span of thegirders. Girder was retrofitted by externally applied of Fiber Reinforced Polymer (FRP) sheet with epoxy resin and alsoinjected the epoxy resin into cracks. After retrofitting tested the girder under same protocol of loading as used beforeretrofitting and check the response of Fiber Reinforced Polymer (FRP) sheet under loading demand. Concluded from thisresearch that externally bonded Fiber Reinforced Polymer (FRP) sheets with epoxy resin and injected of epoxy resin intocracks work effectively and increase the capacity of the girder from 1 times to 1.26 times of the original capacity of thegirder before retrofitting.
