Blast Load Performance of Reinforced Concrete Beams and Columns Constructed with SCC and Fibers

This paper presents the results of a research program investigating the potential of using Self-Consolidating Concrete (SCC) and fibers to improve the blast performance of reinforced concrete structural components. As part of the research program a series of fiber reinforced concrete (FRC) beams and columns constructed with SCC and fibers are tested under simulated blast loading using a high-capacity shock-tube. Test parameters considered include transverse reinforcement detailing, fiber content and fiber type. Under dynamic loading, the combined use of SCC and fibers is found to improve the blast performance of the beams by increasing shear capacity, reducing midspan displacements, increasing damage tolerance. The provision of fibers is also found to improve the blast performance of columns by reducing displacements and eliminating secondary blast fragments.
