This paper investigates the effectiveness of a newly proposed hybrid EB (Externally-Bonded) FRP (Fibre-Reinforced Polymer) wrapping and NSM (Near-Surface Mounted) U-shaped bar (EBNSM) technique to retrofit substandard reinforced concrete (RC) beam-columns joints (BCJ). To do so, this study investigated the behaviour of four full-scale exterior RC BCJs under cyclic loading. The retrofitting schemes considered in this investigation were the EB Glass FRP (GFRP) sheet wraps and the NSM U-shaped steel bar techniques as a comparison benchmark with the specimens retrofitted with the newly proposed EBNSM technique. To do so, one specimen was considered as the unstrengthened control specimen while the second specimen was retrofitted with U-shaped steel bars using the NSM method. The third specimen was retrofitted with EB GFRP sheet wrapping. The fourth was strengthened using the unprecedented hybrid EBNSM method incorporating EB GFRP sheet wraps and NSM U-shaped steel bars. The experimental findings of this study reveal that for all retrofitted BCJs, the strength, loading capacity, and ductility are significantly greater than the control specimen. The specimen strengthened using the NSM, EB, and EBNSM methods showed an increase of 15.3%, 21.8%, and 37%, respectively, in capacity for maximum pull compared to the control specimen. There was a prominent shift in the failure mode from the joint region observed in the control specimen to the unstrengthened beam ends in the retrofitted specimens, especially for EBNSM and EB methods, which would help prevent the structure from disintegrating progressively.
