Abstract: The research progress of flexural fatigue behavior of concrete beams strengthened with Fiber Reinforced Plastic Sheet was summarized, combined with the actual situation that the bridge structures always bear fatigue loads and complex environment, make recommendations and opinions for the research of flexural fatigue behavior of concrete beams strengthened with Basalt Fiber Reinforced Plastic Sheet basing on the Characteristics oflow cost and excellent performance for Basalt Fiber Reinforced Plastic.

Keywords: Fiber Reinforced Plastic Sheet; strengthen; flexural fatigue behavior
