Experimental Investigation and Modeling of the Bond between Aramid Fiber‐reinforced Polymer Bars and Concrete
The main advantages of aramid fiber‐reinforced polymer (AFRP) bars over common reinforcing steel bars are their lightness, durability, mechanical properties and electromagnetic neutrality. For this application, interfacial properties between the reinforcing bar (rebar) and surrounding concrete play a major role in the mechanical performance of the reinforced concrete structure. This chapter investigates the bond behavior of commercially available AFRP rebars embedded in concrete. The first part of the chapter is devoted to the assessment of mechanical and physical properties of the selected rebars. The second part is dedicated to the study of interfacial properties between the rebars and concrete: the interfacial bond strength is first assessed using a specifically designed pull‐out test, and a novel modeling of the interface behavior is then developed, based on an analytic bond‐slip law. The method used for identifying the key theoretical parameters of the model is also discussed.
