State-of-the-art Studies on the FRP-confined Concrete

Abstract

Abstract-The application of FRP in civil engineering has emerged as a popular method of column retrofitting and strengthening. Numerous experimental studies have proven that the confinement with FRP-wrap or tube encasement could enhance the strength, ductility and durability of concrete columns. The variation of each distinct experimental test result to its actual mean value is the general cause of modeling inaccuracy, and this appears to be a lack of consensus among the research community. This paper critically reviewed the current experimental studies with the emphasis on the revelation of the mechanical behavior of FRP-confined concrete and analytical study of its behavior. Lastly, some comments are made on the development trends of study on the mechanical behavior of FRP-confined concrete columns.
