    The use of carbon fibers (CF) and glass fibers (GF) were combined to strengthen concrete flexural members. In this\nstudy, data of tensile tests of 94 hybrid carbon-glass FRP sheets and 47 carbon and GF rovings or sheets were thoroughly\ninvestigated in terms of tensile behavior. Based on comparisons between the rule of mixtures and test data, positive hybrid effects\nwere identified for various (GF/CF) ratios. Unlike the rule of mixtures, the hybrid sheets with relatively low (GF/CF) ratios also\nproduced pseudo-ductility. From the calibrated results obtained from experiments, a new analytical model for the stressââ?¬â??strain\nrelationship of hybrid FRP sheets was proposed. Finally, the hybrid effects were verified by structural tests of concrete members\nstrengthened with hybrid FRP sheets and either carbon or glass FRP sheets.
