摘　　要：纤维增强复合材料(FRP)片材由于其优异的力学性能和施工的便捷性而备受国内外土木建筑领域的高度关注,并得到了迅速的推广应用.本文结合国内外的研究现状及本课题组的研究工作,对FRP片材(纤维布、纤维板和纤维薄板)在土木建筑修复加固工程中应用的主要力学问题-FRP片材加固钢筋混凝土(RC)构件的静力学性能、疲劳性能、界面的力学性能、以及构件的耐久性等进行综述和讨论,并试图指出今后有关FRP片材修复加固RC构件力学性能的研究方向.A large number of researches and applications in civil and construction engineering have been focused on fiber reinforced plastic （or fiber reinforced polymer, FRP）, because of FRP＇s excellent mechanical properties and their constructional convenience. In this paper, based on some previous researches by authors and the present studies on FRP laminate （fiber sheet, fiber plate or fiber laminate） applied in civil and construction engineering for repairing and strengthening in the world, some key mechanical problems of the strengthened structures with FRP, such as the static mechanical properties, fatigue performances, the mechanical properties of the interface between FRP and RC members, and the durability of the strengthened structure are summarized and discussed. Some developmental ways are also proposed.
