摘要
In order to discuss the fatigue property of reinforced concrete (RC) beams strengthened with fiber reinforced polymer (FRP) in highway bridge under the overload, this article focuses on 20m hollow slab simply supported beam bridge in highway of Guangzhou, defined the highway overload for vehicle loading, and three steps ladder spectrum of the overload was generated.And then, the fatigue testing method of the RC beams strengthened with carbon fiber laminate (CFL) using the ladder spectrum of the overload was proposed, the fatigue testswere carried out successfully, and the S ~N curves and the fatigue equations were obtained.
