The main objective of this study to increase the durability of beam by using the various
types of jacketing techniques. In this research, I am considering the two methods for
retrofitting the beams, i.e. the first method is Reinforced Concrete jacket (RC), other is
carbon fiber reinforced polymer jacket (CFRP). In this study, 100 mm thickness of RC
jacketing is used at all four sides of the beam while the CFRP with different thickness of
sheet are used. After casting the beams, the point load test is done on loading frame
machine and check the crack, ultimate strength in the beam and comparing the results and
cost of all different types of retrofit techniques for reinforced concrete. The Analyses have
also performed in ABAQUS software and then validation is done by comparing the
deformation and stress behavior in ABAQUS and experimentally. The conclusion of this
study shows that the RC jacketing strength increased by 63% where as in CFRP it
increases by 48.5%. The test results show that the RC jacketing gain more strength then
other jacketing methods and increase the flexural strength.
