Abstract

During the last two decades, fiber reinforced polymer (FRP) reinforcing bars have been extensively investigated and a number of FRP bars are now commercially available. However, the use of FRP bars as internal reinforcement in concrete structures is still unfamiliar to many practicing Australian engineers. This paper provides an overview on the current research and developments on FRP bars to ensure that Australia is properly informed in the engineering research for this advanced material allowing its responsible introduction and wide use in civil infrastructure. Firstly, research and developments on the application of FRP bars as internal reinforcement in concrete beams, columns and slabs are presented. Secondly, the results of the on-going efforts on the evaluation of the potential use of FRP bars in geopolymer concrete structures are discussed. Thirdly, the concept of material hybridization to develop a viable hybrid FRP bar for concrete structures was presented. Finally, some field applications of the GFRP bars to a number of civil infrastructures in Australia were highlighted.
