چکیده مقاله
One of the most prominent challenges of flexural strengthening of beams using Fiber Reinforced Polymer FRP composites, is the premature debonding of FRP laminate from concrete substrate, which makes the strengthening calculations less reliable The new Externally Bonded Reinforcement In grooves EBRIG method, being recently developed at Isfahan University of Technology IUT , has yielded completely satisfactory results in postponing premature debonding of FRP laminates in concrete beam specimens without internal flexural bars In the current study, the performance of EBRIG method in reinforced concrete beams has been evaluated To reach the aforementioned purpose, five reinforced beam specimens with dimensions of 120×140×1000 mm were cast and externally strengthened with the conventional Externally Bonded Reinforcement EBR and new EBRIG methods Beams were then subjected to four point flexural loading As a means of comparison, one reinforced beam without any external strengthening was also tested The Experimental results showed a significant increase in the failure load of the beam strengthened with multi FRP layers using EBIRG method
