摘要
One of the most promising applications of fiber reinforced polymer (FRP) composites is in reinforced concrete columns. This paper provides a review of recent research in this area. Based on the literature available, it is found that most applications and research are focused on the FRP retrofit or repair of existing reinforced concrete columns primarily for improved ductility. Some recent research efforts have been directed to the new design of columns using FRP tubes or FRP bars. The use of FRP tubes is reviewed in comparison to previous research on concrete filled steel tubular (CFT) structures and the tubed structures. It is more likely favorable for the FRP tube or rebar to be used as transverse reinforcement of concrete columns for better ductility needed for seismic design. A new concept by the author on confined concrete filled tubular (CCFT) columns is also introduced along with promising test results.
