Fatigue Behavior of Stirrup Free Reactive Powder Concrete Beams Prestressed with CFRP Tendons

A comprehensive study on the fatigue behavior of stirrup free reactive powder concrete (RPC) beams prestressed with carbon fiber-reinforced polymer (CFRP) tendons is presented in this paper. A total of six specimens were tested, and the effects of the shear span/depth ratio, load amplitude, and steel fiber content on the fatigue behavior of the beams were analyzed. The test results showed that the fatigue damage evolution of the RPC beams...
