Stainless Steel Bonded to Concrete: an Experimental Assessment using the DIC Techniquebond failureconcretedigital image correlationstainless steelCivil and Structural EngineeringOcean EngineeringThe first author of this work would like to express his deepest gratitude to Fundacao para a Ciencia e Tecnologia for the partial financing of this work under the UNIDEMI Strategic Project PEst-OE/EME/UI0667/2014 and for the post-doctoral grant SFRH/BPD/111787/2015. The second author is also grateful to UNIDEMI for his scientific research grant under the Strategic Project UID/EMS/00667/2013.The durability performance of stainless steel makes it an interesting alternative for the structural strengthening of reinforced concrete. Like external steel plates or fibre reinforced polymers, stainless steel can be applied using externally bonded reinforcement (EBR) or the near surface mounted (NSM) bonding techniques. In the present work, a set of single-lap shear tests were carried out using the EBR and NSM bonding techniques. The evaluation of the performance of the bonding interfaces was done with the help of the digital image correlation (DIC) technique. The tests showed that the measurements gathered with DIC should be used with caution, since there is noise in the distribution of the slips and only the slips greater than one-tenth of a millimetre were fairly well predicted. For this reason, the slips had to be smoothed out to make it easier to determine the strains in the stainless steel and the bond stress transfer between materials, which helps to determine the bond–slip relationship of the interface. Moreover, the DIC technique allowed to identify all the states developed within the interface through the load–slip responses which were also closely predicted with other monitoring devices. Considering the NSM and the EBR samples with the same bonded lengths, it can be stated that the NSM system has the best performance due to their higher strength, being observed the rupture of the stainless steel in the samples with bond lengths of 200 and 300 mm. Associated with this higher strength, the NSM specimens had an effective bond length of 168 mm which is 71.5% of that obtained for the EBR specimens (235 mm). A trapezoidal and a power functions are the proposed shapes to describe the interfacial bond–slip relationships of the NSM and EBR systems, respectively, where the maximum bond stress in the former system is 1.8 times the maximum bond stress of the latter one.DEC - Departamento de Engenharia CivilUNIC - Centro de Investigação em Estruturas e ConstruçãoRUNBiscaia, HugoFranco, NoelChastre, Carlos2019-01-25T23:37:09Z2018-12-012018-12-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://doi.org/10.1186/s40069-018-0229-8eng1976-0485PURE: 3714727http://www.scopus.com/inward/record.url?scp=85041297364&partnerID=8YFLogxKhttps://doi.org/10.1186/s40069-018-0229-8info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-05-22T17:36:50Zoai:run.unl.pt:10362/58644Portal AgregadorONGhttps://www.rcaap.pt/oai/openairemluisa.alvim@gmail.comopendoar:71602024-05-22T17:36:50Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
