In recent years, FRP （fiber-reinforced polymer/plastic） has been widely utilized for strengthening concrete structures due to its high tensile property. FRP has attracted much attention by the civil and construction industry since it is considered as a new type of high performance structural material. Many research works and actual applications of FRP to civil structures were carried out by both domestic and international organizations. In this paper, an introduction is given on the properties and different forms of FRP frequently used for structural applications, including the statements on the advantages and drawbacks of the material. Moreover, a brief review is given on the application and future development of FRP used for strengthening structures, FRP reinforcements and prestressed tendons for concrete structures, FRP composite structures and other FRP structures, such as bridges, large-span structures and intelligent structures. This paper is mainly aimed at promoting future research and application of FRP for civil structures in China.
