Innovative techniques based on fibre reinforced polymer (FRP) laminates externally bonded to existing structures appear to be interesting alternatives to traditional solutions for the seismic upgrade and repair of buildings and civil structures. Interface failures represent a typical issue of FRP laminates externally applied to reinforced concrete elements, due to high stress concentrations in the anchorage zone of most types of application. Experimental tests to evaluate the efficiency of anchorage systems to avoid the delamination failure at the end of FRP laminates have been performed. Efficiency of the anchorage is evaluated either in terms of ultimate strength or in terms of ductility of the system
