【Abstract】 A large number of researches and applications in civil 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 the authors’ previous researches and present studies on FRP sheet (or fiber sheet) applied in civil engineering, some key mechanical problems of the strengthened structures with FRP, such as bending strength, shearing strength, fatigue strength, and the strength of the interface between the fiber sheet and concrete members, are summarized and discussed. Some developmental ways are also proposed.更多还原
