GFRP reinforced concrete beams are more and more popular in the construction industry due to its non-corrosive behaviors. The needs for shear flexural and axial strengthening of GFRP-reinforced concrete structures would come from the demands of the owner in altering the using functionality of the building. These demands could even happen during the construction stage. This paper presents the experimental study related to the use of textile reinforced concrete TRC in shear strengthening of GFRP reinforced concrete beams. Two identical GFRP reinforced concrete beams with an aspect ratio a d of 1 7 and no stirrups are tested in this study. These are control and shear strengthened beams. The experimental results show that TRC is effective in enhancing the shear strengths of GFRP reinforced concrete beams. The experimental shear strengths of strengthened and control beams are compared with the existing equations from ACI 318-19 and debonding model. The analytical shear strengths show satisfactory results. Keywords GFRP reinforced concrete beam shear strengthening textile reinforced concrete shear strength. 2021 University of Transport and .
