More recently, a new technique, re-9 ferred to as externally bonded reinforcement on grooves (EBROG), has been proposed, which is based 10 on using a number of grooves throughout the concrete substrate with the aim of enhancing the bond 11 strength between the FRP composite and concrete. This study investigates the influence of groove depth 12 on the resulting debonding process that can be observed in prestressed carbon FRP strips. To do so, 13 prestressing force release tests were conducted on a series of EBR and EBROG FRP strips bonded to 14 concrete specimens. Test results demonstrated that the fracture process leading to debonding of the 15 EBROG specimens developed in a significantly different manner with respect to the case of EBR spec-16 imens. Specifically, fractures ran through deeper layers of concrete as the grooves became deeper.

Experiments were performed on nine RC beams: one beam was not exposed to fire (control specimen) and eight beams were divided into two groups exposed to fire for 30 and 60 min. In each group, one beam was not retrofitted, whereas the other three beams were retrofitted using NSM GFRP. After retrofitting, all beams were loaded until failure. The experimental results confirmed that the retrofitting technique effectively recovered the strengths of postfire RC beams. The failure mode of the GFRP retrofitted beams was the peeling-off of concrete cover, whereas that of the control and unretrofitted postfire beams was flexural failure via the yielding of tension steel. The NSM GFRP retrofitting fully recovered or significantly increased the yield and ultimate strengths of postfire RC beams by up to 39%. The yield deflection capacity of the NSM GFRP retrofitted postfire beams was much higher than that of the control beam; however, the ultimate deflection capacity of these beams significantly decreased. Consequently, the GFRP retrofitted postfire beams were of low ductility because of the peeling-off of the concrete cover. NSM GFRP retrofitting slightly improved but did not completely recover the yield stiffness reduced by fire, whereas it increased the plastic stiffness significantly by up to threefold. An analytical model for estimating the yield moment of postfire RC beams without/with NSM GFRP retrofitting was proposed, considering the very limited information, for example, fire duration obtained from actual fire events. The practicality and reasonable accuracy of the proposed model render it beneficial for structural engineers.","PeriodicalId":15540,"journal":{"name":"Journal of Composites for Construction","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136062390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
