Abstract: In order to avoid failure of concrete structures due to steel corrosion its pertinent to have an alternative material which provides durability, requisite serviceability and is also economical at the same time. FRP rebar is one such material which is being researched extensively and being incorporated in place of steel in concrete construction in many countries like Canada, Japan, New Zealand to name a few. With the increased use of FRP reinforcement in concrete structures, it is necessary to establish appropriate design guidelines for various FRP-RC members. In particular, stability of FRP-RC columns and applicability of using FRP ties as transverse confinement material . In this study, the behaviour of concrete columns reinforced by steel bars as longitudinal reinforcement and GFRP bars as transverse confinement reinforcement is investigated based on laboratory tests on one third size specimens The confinement parameters being ratio of transverse reinforcement , tie spacing , tie configuration, yield strength of transverse reinforcement and longitudinal reinforcement. The test results show that post corrosion the GFRP specimens show better ductility and toughness than conventional all steel RC specimens.
