| Abstract | ||||
| Self-compacted concrete (SCC) is a recent application of reinforced concrete. Some properties of this type of concrete are recently studied. In this work the ductility of self compacted reinforced concrete beams was investigated experimentally. Where nine reinforced concrete beam models 10x20x170 cm were cast and tested till failure. The parameters taken into consideration were the methods of strengthening using FRP and steel systems. Where eight different strengthened methods were used including glass fiber reinforced polyester, carbon fiber wrap reinforced polyester and galvanized steel plates. Recorded measurements including cracking loads, ultimate loads, deflection, rotation and modes of failure. The experimental results show that the self-compacted concrete have a good mechanical properties rather than normal strength concrete. The results indicated that the FRP strengthened systems enhancing ductility behavior of self- compacted concrete beams, increasing cracking loads, ultimate loads, cracking distributions and control modes of failure. Comparison between the experimental results and the theoretical ones using ACI 440-2R-02. was performed and discussed. | ||||
