Abstract
Concrete has been extensively used as a protective structure to resist blast and impact loads for many years. Recently, to increase the impact resistance of concrete, research related to the development of various strengthening methods increasing the use of steel fibers and fiber reinforced polymers (FRPs) has been actively performed. In this study, the compressive and flexural behaviors of normal strength concrete (NSC) and steel fiber reinforced concrete (SFRC), which includes 30 mm long hooked steel fibers in volume fractions of 0.5, 0.75, 1.0, 1.25 and 1.5%, were evaluated under static loading conditions. In order to investigate the flexural strengthening effect of externally bonded FRP sheets and steel fibers on one-way slabs in a high strain rate range conditions, the impact tests were performed using a drop-weight impact testing machine. Test results indicated that the flexural resistance of concrete is significantly improved by strengthening with FRP sheets and steel fibers.
