This paper deals with an experimental study on the tensile performance of recently developed “FRP Hybrid Bars” by authors. The objective of this study is to investigate tensile strength of FRP Hybrid Bars. FRP Hybrid Bar uses the concept of material hybridization to increase elastic modulus to be used in concrete structures, especially for marine and port concrete structures. The effect of hybridization on tensile properties of FRP Hybrid Bars was evaluated by comparing the results of tensile test with those of non-hybrid FRP bars. The results of this study indicated that the elastic modulus of the hybrid GFRP bar was increased by up to approximately 5 to 204 percent by the material hybridization.
