摘　　要：FRP(纤维增强复合材料)近年来在混凝土结构加固中得到广泛的应用,并作为一种新型高性能结构材料受到结构工程界的广泛关注,国内外有关研究和工程单位开展了大量的研究和实践应用。本文介绍了结构工程中常用的FRP材料性能和形式,分析了其优点与不足,并介绍了FRP加固结构、FRP配筋和预应力FRP筋混凝土结构、FRP结构与FRP组合结构以及FRP在桥梁结构、大跨空间结构和智能结构中的应用与发展,以期促进我国土建结构工程中对这一新型高性能材料应用和研究工作的开展。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.
