With this method, it is not necessary to attach many strain gauges on the FRP sheets for obtaining the strain distributions in FRP as well as the local bond stresses and slips. Instead, the local interfacial bond stress-slip models can be simply derived from the relationships between the pullout forces and loaded end slips. Based on a series of pullout tests, the bond stress–slip models of FRP sheet–concrete interfaces, in which different FRP stiffness, FRP materials (carbon FRP, aramid FRP, and glass FRP), and adhesives are used, have been derived. Only two parameters, the interfacial fracture energy and interfacial ductility index, which can take into account the effects of all interfacial components, are necessary in these models. Comparisons between analytical results and experimental ones show good accordance, indicating the reliability of the proposed method and the proposed bond stress–slip models.American Society of Civil Engineers2005engjournal articleAMhttp://hdl.handle.net/2115/5921https://doi.org/10.1061/(ASCE)1090-0268(2005)9:1(52)1090-0268Journal of Composites for Construction915262https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/5921/1/JCC9-1.pdfapplication/pdf628.48 KB2005
