Bond Behavior at the Interface in Concrete Elements Strengthened with NSM bars and Strips

The paper presents the results of experimental monotonic Single Shear Tests (SST) on concrete prisms reinforced with basalt, glass and carbon bars/strips according to the NSM technique. The experimental tests are a part of wide Round Robin Test programme involving several research laboratories. The tests are aimed to define the ultimate load and to characterize the bond behaviour of NSM strengthening systems in concrete elements at varying several parameters (material, geometry, surface treatment)
