Indirect Identification of the Bond-Slip Model at SRP-Concrete Interface
Steel Reinforced Polymer (SRP) systems represent an appealing solution for the external strengthening and repairing of existing reinforced concrete structures. However, similarly to what known for composite materials employing other fibers, such as carbon or glass ones, to assure an adequate bond between the reinforcement and the concrete substrate is fundamental for the success of many strengthening applications. In this paper, an analytical procedure recently published by the authors is applied for an indirect identification of the concrete-SRP interface law by varying some parameters, such as the compressive strength and the surface finish of the concrete. To this purpose, results from a wide experimental campaign performed by the authors have been considered. The bond-slip laws found case by case, implemented in the analytical procedure, allow for accurately fitting the experimental load-slip curves obtained from the performed direct shear tests.
