| An attempt has been made to study the response of under shear reinforced concrete (RC) beams with varying strength concrete under static and impact load. The experiment has been performed on beam strength as 20, 30, 40 and 50 MPa having cross sections of 50 x 100 mm with a span of 1.1 m. Also, a benchmark study was performed under four-point bending static test and further, three-point bending were converted theoretically in order to keep the test configuration equivalent to three-point impact load test for the comparison. The resistance of reinforced concrete beams was studied in terms of impact force versus time and the deformed profile. It was observed that the resistance of beams was found to increase with increasing the strength of concrete; however, the beams were failed by shear, the reason may be due to the lack of shear capacity. The peak static force by four point bending tests found to be 33% higher than three point bending tests. It was also observed that the dynamic amplification factor (DAF) increases with increase of concrete strength and highest DAF found to be 4.75 corresponding M50 concrete whereas the same was found to be 3.5 corresponding M20 concrete. | ||
