The Attitude of Load-Deflection for Concrete Beams with Polymer Reinforcement

In this research, the load-deflection behavior is explored for concrete beams reinforced with FRP bars (polymer reinforcement). An experimental test done a total of five subjected to 4-point loading. The tested specimens are dimensions; 2100 mm (length), 200 (width) and 300 (depth), while used compressive strength f’c = 60 MPa. Four were longitudinally by various CFRP rebar numbers, last beam was only steel as control beam. Relationships drawn influence several factors debated on relationship. It exhibited that failure samples generally ruled strength. When ratio reinforcement rising 50%, 100% 150%, ultimate load increased 15%, 29% 38%, respectively, recorded deflection at decreased 7%, 16% 24%, respectively. For studied beams, outcomes equations American code ACI 440.1R give very close values values, they conservative which smaller than about (37%-45%).
