This article presents an experimental campaign on full scale RC beam–column joints subjected to cyclic loading. A joint specimen, belonging to a 4-storey RC framed building designed to only withstand gravity loads, was firstly tested without retrofitting elements. It was then damaged and re-tested after the application of a retrofitting system named DIS-CAM. The main objective of the intervention was to increase the seismic performance of the joint in such a way as to achieve the same response as that of a joint which has been seismically designed in accordance with the Italian code for a peak ground acceleration equal to 0.25 g. A companion seismic specimen was purposely designed and tested to facilitate a direct comparison in the analysis of the effectiveness of the retrofitting technique. The paper describes the design and the execution of the retrofitting intervention which does not require particular …
