- Abstract:
-
The difference in the properties of fiber polymer reinforcement and steel bar makes the bonding performance of fiber polymer reinforced concrete significantly different from that of reinforced concrete. According to the force transmission mechanism between fiber polymer reinforcement and concrete, the relationship between bonding stress, fiber polymer reinforcement stress and anchorage length is discussed, and the basic formula for calculating the bonding of fiber polymer reinforced concrete is established. On the basis of summarizing the existing bond-slip constitutive models of fiber polymer reinforcement and concrete at home and abroad, a continuous curve constitutive model of bond-slip is proposed. The model is based on the three key points of the bond-slip curve, and the physical concept is clear, smooth and continuous. Finally, the calculation of anchor length is discussed, and the calculation method of anchorage length is suggested.
