000011168 520__ $$2eng$$aExternal bonding of fibre reinforced polymer (FRP) composites has become a popular technique used worldwide for strengthening existing reinforced concrete structures. A key factor for the effectiveness of such technique is the bond of FRP reinforcement to the concrete substrate; numerous experimental works have been carried out to investigate such aspect. In particular, different test set up layouts, namely single shear test, double shear test and beam test, respectively, have been used to determine the maximum force which can be carried out by external reinforcement, the bond stress–slip relationship and the fracture energy of the interface law. However, experimental data concerning cyclic tests on both FRP sheets or plates applied on concrete specimens are still lacking. Thus a series of Single Shear Test (SST) under both monotonic and cyclic actions, without inversion of sign, have been performed on concrete prismatic specimens (characterized by a low compressive strength in order to simulate the application on existing structures to be strengthened) reinforced with CFRP sheets and plates. In order to evaluate and compare the influence of cyclic external actions on the bonding behaviour of both sheets and plates reinforcements, the monotonic and cyclic tests results have been reported and analyzed in the paper in terms of force-displacement curves, axial strains and shear stresses recorded during the tests along the FRP reinforcement; the influence of the load path on the FRP debonding behaviour has been also examined.
