Two Type of Impact Load Tests, Tested on Fibre Reinforced Concrete Specimens

Fibre-reinforced composite materials are becoming important in many areas of technological application. In addition to the static load, such structures may be stressed with short-term dynamic loads or even dynamic impact loads during their lifespan. Dynamic effects can be significant especially for thin-walled shell structures and barrier constructions. Impact loading of construction components produces a complex process, where both the characteristics of the design itself and the material parameters influence the resultant behavior. It is clear that reinforced concrete with fibers has a positive impact on increasing the resistance to impact loads. However, the assessment of the increase of this resistance has not been sufficiently verified experimentally. Results of impact load tests carried out on prisms with different amount of the fibers and drop-weight impact tests are presented in this paper.
