| Abstract: | As a new material,FRP has been rapidly finding wider and wider applications in actual structural fatigue reinforcement as its price drops.The present paper mainly focuses on introducing the experimental studies and theoretical analyses of the flexural fatigue behavior of RC beams strengthened with different FRP sheets both at home and abroad.With the experiments on RC beams strengthened with BFRP sheets performed by our group as practical examples,put forward in the paper are some useful suggestions on the future orientation of the study of the flexural fatigue behavior of RC beams strengthened with FRP sheets,which may favor the development of the subject in the future. |
