Efficiency of shear strengthening of RC beams with externally bonded FRP materials: state-of-the-art in the experimental tests

This paper presents a study of the shear capacity of reinforced concrete (RC) beams strengthened in shear with externally bonded (EB) fiber reinforced polymer (FRP) composites, based on the performance of existing published tests. The main objective of this study is to create a comprehensive overvie...

The main objective of this study is to create a comprehensive overview of the performance of different shear strengthening configurations and the failure modes observed in experimental tests. In addition, the influence of the following parameters on the strengthening efficiency has been analyzed: shear span to depth ratio (a/d), existing steel transverse reinforcement ratio (ρsw), concrete strength (fck), size effect (d), longitudinal reinforcement ratio (ρsL), strengthening configurations, type of FRP: sheets or laminates (CFRP, GFRP), and FRP axial stiffness (AfEf).This paper has been developed under the framework of the Research Projects “BIA2015‐64672‐C4‐1‐R” and “RTI2018‐097314‐BC21” funded by the Spanish Ministry of Economy and Competitiveness (MINECO) and co‐funded by the European Regional Development Funds (ERDF). The authors would also like to thank the Cost Action TU1207 which funded a short term scientific mission of the second author in Lodz University of Technology.Peer Reviewed20212021-07-0120212021-04-07journal articlehttp://purl.org/coar/resource_type/c_6501AMhttp://purl.org/coar/version/c_ab4af688f83e57aainfo:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/2117/343239https://dx.doi.org/10.1016/j.compstruct.2021.113891reponame:UPCommons.
