COMPARATIVE STUDY OF BEAMS BY USING DIFFERENT TYPES OF RETROFITING TECHNIQUES

The main aim of this study was to increase the strength of beams by using different types of jacketing techniques and checks the most cost-efficient methods. In this paper, the reinforced concrete (RC) jacketing and carbon fiber reinforced polymer jacketing was used for retrofitting the beams. In this research study, 100 mm thickness of RC jacketing is used in all four sides of beam and carbon fiber reinforced polymer (CFRP) of different thickness of sheet are used. The point load test is done on loading frame machine and check the crack, ultimate strength and comparing the results and cost of all different types of retrofit techniques for reinforced concrete. Analyses was also performed on ABAQUS software and then validation is done by comparing the deformation and stress behavior in ABAQUS and experimentally. It was observed that the RC jacketing strength increased 63% and 48.5% strength increase in CFRP. The test results show that the RC jacketing gain more strength then other jacketing methods and increase the flexural strength.
