The response of concrete for dynamic loading is of interest in a variety of civilian and military applications. Characterization of the behavior of concrete under dynamic loading is a prerequisite for the design and analysis of these structures. This paper present the results of a series of experiments conducted to investigate the rate sensitivity and the effectiveness of fiber inclusions in the improvements of fracture toughness of High Performance Concrete (HPC)beams. Single-edge notched beams (0.5 notch ratio) were loaded in three point bending over a wide range of displacement rates (Do).
Load-displacement curves show that their peak is higher as the Do increases, whereas the corresponding displacement is almost constant. Fracture energy, G f also increases but only under Do beyond a threshold value. The experimental finding of the present work addressed the positive roles of fibers (steel and polypropylene) in improving the performance of concrete under dynamic loading.
