EXPERIMENTAL INVESTIGATION OF CONCRETE BEAMS REINFORCED WITH GFRP BARS

Glass fiber reinforced polymers (GFRP) reinforcement bars has a lower stiffness than steel reinforcement, which should be accounted for the ultimate and serviceability conditions, including the impact on member deflection and crack widths. This paper presents an experimental study of the flexural behavior of concrete beams reinforced with locally produced glass fiber reinforced polymers (GFRP) bars. The bars are locally produced by double parts die mold using local resources raw materials. A total of seven beams measuring 120 mm wide x 300 mm deep x 2800 mm long were caste and tested up to failure under four-point bending.
