| Concrete structures present brittle behavior against impulsive actions, like rock fall impacts, explo-sions or other causes. These actions release suddenly large amounts of energy. Fiber addition to con-crete enhances its energy absorption capacity, thereby increasing its performance against impact loads. In order to study influence of fiber addition in the behavior of concrete structures, an experi-mental campaign has been carried out on four concrete reinforced beams without stirrups. Conven-tional concrete and steel fiber-reinforced concrete (FRC) specimens were tested under impact and quasi-static conditions. Tests results suggested that under quasi-static conditions FRC beams were 40 % stronger than conventional concrete, showing a ductile behavior after shear crack development. Impact tests indicated that FRC beams are more capable to absorb impact energy without shattering. FRC energy absorption capacity under impact is almost a 300 % than that of concrete. | |
