Abstract：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.
