摘　　要：FRP作为一种新兴材料,其在实际结构疲劳加固中的应用随着价格的降低而飞速发展。主要介绍了国内外关于不同FRP布加固钢筋混凝土梁弯曲疲劳性能的试验研究与理论分析,结合课题组进行的玄武岩纤维布(BFRP)加固RC梁试验情况,为今后FRP布加固RC梁弯曲疲劳性能的研究方向提出几点建议,有利于该学科的发展。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.
