    Abstract

    Abstract: This study examines the shear strength characteristics of deep reinforced concrete beams without shear reinforcement strengthened with glass fiber sheets. Tests were performed to determine whether an externally bonded RC deep beam with GFRP sheets would fail. The Four-point static loading approach was applied for the experiment. In order to investigate the effects of the factors (glass fiber sheets and shear span to depth ratio (a/h)), six reinforced concrete deep beams were tested. Deep beams were strengthened using GFRP sheets. The GFRP type used was Chopped Strand Mat glass fiber sheet (CSM). The test result indicated that the increase of a/h lead to decrease the ultimate shear capacity, while the ultimate shear capacity increases with strengthening the deep beams with glass fiber sheets polymer. The chopped strand mat (CSM) GFRP increased the shear capacity of the deep beams compared to control beam in group (I, II and III), the increase in strength was (81%, 67% and 62%) respectively, therefore, it is recommended to use (CSM) sheets in deep beam strengthening.
