Cracks in reinforced concrete sections can lead to sudden and total failure from which recovery is impossible. This results in change in the physical characteristics of a structure and thus the static and dynamic response also varies. Depth of crack and its location are the main parameters for the analysis of the cracked beam. It becomes very important to know the changes in these parameters of the structure in order to access its reliability, performance and safety. The use of externally bonded composite sheets is to strengthen existing reinforced concrete structure and hence it improves the service life of the structure. In this paper, the static characteristics of cracked reinforced concrete beam are examined by finite element analysis using ANSYS. Also, comparison between normal beams and cracked beams retrofitted with FRP under various conditions including FRP as sheet below the cover, FRP sheet as cover, FRP as strip below the cover, FRP strip instead of cover and grooving of FRP into the concrete are studied in this paper. It may be concluded that FRP Strip Removing Cover has better result in case of both maximum principal stress and minimum total deformation. The studies were performed using ANSYS 16.
