Flexural Retrofitting of RC Beams Using Extra Rebars and U-Wraps

Abilash George Varughese | T. Manikandan


Abstract: More recently, near-surface mounted (NSM) FRP reinforcement has attracted an increasing amount of research as well as practical application. In this experimental study, the effectiveness of NSM bars as a means of restoring or upgrading the flexural capacity of RC beams is investigated. A total of nine beam specimens of grade M20, length 1m and cross-section of (150mmx200mm) were casted and tested by two point load method. Out of these, beams were retrofitted with steel rods and GFRP rods using Near Surface Mounted (NSM) technique, externally bonded with FRP U-wraps after applying 75 % of the ultimate load. A comparative study was made with the test results.
