This work presents an experimental campaign to investigate the effect of sustained load, bonded length and groove width on the time-dependent behavior of concrete strengthened with NSM CFRP strips. Single shear pull-out tests have been carried out. Both instantaneous and time-dependent slip values were found to be affected by the investigated parameters, and the increase of slip due to bond deterioration was more accentuated in those specimens loaded at 50% of sustained load than those at 25% 2024-06-13T09:51:34Z 2024-06-13T09:51:34Z 2024-06-13T09:51:34Z 2017 info:eu-repo/semantics/conferenceObject http://hdl.handle.net/10256/17765 Tots els drets reservats info:eu-repo/semantics/openAccess International Union of Laboratories and Experts in Construction Materials, Systems and Structures Contribucions a Congressos (D-EMCI)
