This paper introduces the recent development of GFRP-steel hybridized rebar and deals with an evaluation of its mechanical performance by authors. The objective of this study is to investigate tensile and bonding performance of the GFRP-steel hybridized rebar. The effect of hybridization on tensile properties was evaluated by comparing the results of tensile test with those of non-hybrid GFRP bars. The surface of the bar was designed and experimentally evaluated to obtain the sufficient bond strength in this study. To ensure the long-term durability of GFRP-steel hybridized rebar to corrosion resistance, the individual and combined effects of environmental conditions are currently under investigation.
