This paper presents an experimental study on the effect sustained loading and different service temperatures (steady and cyclic) have on NSM Carbon Fibre-Reinforced Polymer (CFRP)-concrete bonded joints and their post-sustained loading load-slip behaviour. Four experimental campaigns using eight NSM CFRP-concrete specimens were performed by employing two different service load levels (15% and 30% of the ultimate load) and combining two groove thicknesses (7.5 and 10 mm) and two bonded lengths (150 and 225 mm). Two steady state temperatures (20 and 40 °C) and two cyclic service temperatures (ranging between 20 and 40 °C) were programmed. The slip obtained was proportional to the sustained load level. Furthermore, higher slips were registered for specimens under higher mean temperatures in the cycle. After 1000 h of sustained load testing, the specimens were tested under monotonic loading until failure (post-sustained loading tests). In general, the ratio between the post-sustained loading ultimate load and the instantaneous ultimate load was close to the unity, although some differences were perceived in series S2 (steady 37.7 °C) with a mean increase of 6.3%, and series S3-B (cyclic temperature ranging between 24.6 and 39.2 °C) with a mean reduction of 9%" , "dc.description.sponsorship": "This research was funded by the Spanish Ministry of Science, Innovation and Universities, (projects BIA2007-84975-S2-2-P and BIA2007-84975-S2-1-P) and the University of Girona (grant number IFUdG2018/18)" , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "MDPI (Multidisciplinary Digital Publishing Institute)" , "dc.relation": "BIA2007-84975-S2-2-P" , "dc.relation": "BIA2007-84975-S2-1-P" , "dc.relation.isformatof": "Reproducció digital del document publicat a: https://doi.org/10.3390/app11188542" , "dc.relation.ispartof": "Applied Sciences, 2021, vol. 11, núm. 18, p. 8542" , "dc.relation.ispartofseries": "Articles publicats (D-EMCI)" , "dc.rights": "Attribution 4.0 International" , "dc.rights.uri": "http://creativecommons.org/licenses/by/4.0/" , "dc.subject": "Assaigs de materials" , "dc.subject": "Materials -- Testing" , "dc.subject": "Formigó armat -- Proves" , "dc.subject": "Reinforced concrete -- Testing" , "dc.subject": "Resistència de materials" , "dc.subject": "Strength of materials" , "dc.title": "Sustained Loading Bond Response and Post-Sustained Loading Behaviour of NSM CFRP-Concrete Elements under Different Service Temperatures" , "dc.type": "info:eu-repo/semantics/article" , "dc.rights.accessRights": "info:eu-repo/semantics/openAccess" , "dc.type.version": "info:eu-repo/semantics/publishedVersion" , "dc.identifier.doi": "https://doi.org/10.3390/app11188542" , "dc.identifier.idgrec": "033842" , "dc.type.peerreviewed": "peer-reviewed" , "dc.identifier.eissn": "2076-3417" }
