CURVED NON FERROUS REINFORCEMENT FOR CONCRETE STRUCTURES
Abstract The mechanical properties of composite reinforcing elements differ from those of conventional steel rebars in a number of ways. As a result, several issues need to be taken into account when designing concrete elements reinforced with composite reinforcement. For example, it has been proven experimentally that the capacity of curved composite elements can be considerably lower than that of their straight counterparts. This paper reports on an experimental study that was carried out at the University of Sheffield to investigate the capacity of curved composite reinforcing elements. Direct pull-out tests were performed on thermoplastic composite strips embedded in concrete cubes. A total of 47 specimens and 19 different configurations were tested. The parameters that were investigated included geometry of the bend, surface treatment, embedment length and concrete strength. This paper presents the preliminary findings of this experimental investigation as concerns the problems related to the use and performance of curved FRP bars in concrete.
