CHARACTERIZATION OF ARAMID FRP REBARS AND STUDY OF THEIR BOND BEHAVIOUR WITH CONCRETE
This research aims at investigating the suitability of Aramid Fiber Reinforced Polymer
(AFRP) bars for the reinforcement of concrete structures. The first part of the paper is devoted to the
assessment of mechanical and physical properties of the selected commercially available AFRP
reinforcing bars (rebars). A second part is then dedicated to the study of interfacial properties between the rebars and concrete: the interfacial bond strength is first assessed using a specifically designed pullout test, and a modelling of the interface behaviour is then developed, based on an analytic bond-slip constitutive law. The method used to identify parameters of the model is also discussed in detail.
