Abstract
![CDATA[This research project is on utilization of synthetic fibres as intrinsic reinforcement in reinforced concrete beam in order to evaluate the structural behaviour of such element under cyclic loadings. The invaluable goal of this project is to improve the ductility and damping of the concrete beam element. The former helps eliminate or reduce the need for steel reinforcement in concrete structures and the latter provides characteristics with which the structure itself can be responsible for the dynamic loads, therefore the extra costs for external dampers can be eliminated. A simply supported beam approximated as a single degree of freedom system (SDOF) is tested and analysed as part of this project. In such systems there is only one direction of movement defined for a mass under dynamic loads. Hysteresis loops are gathered by applying cyclic loads the results of which are analysed to evaluate the performance of fibre matrix in reinforced beam comparing to the conventional concrete. Results show that by adding Polypropylene fibres by specific percentages, it is possible to improve not only the mechanical performance of reinforce beam but also the behavior of the structural beam under dynamic loads. The behaviour of such beams demonstrated elevated performance to a considerable extend when PP fibres are included in the mix design.]]
