- Abstract:
-
According to the mechanical properties of fiber-reinforced plastic reinforcement (FRP bar) and its concrete beam, the expression of the cross-sectional curvature of the fiber-reinforced plastic reinforced concrete beam to achieve the nominal yield strength of the fiber-reinforced plastic reinforcement and the cross-sectional curvature of the final failure of the beam was established. Based on this, the calculation method of section curvature ductility of fiber-reinforced plastic reinforced concrete beams is discussed. The results show that the curvature ductility coefficient of fiber-reinforced plastic reinforced concrete beams increases with the decrease of the reinforcement ratio of fiber-reinforced plastic reinforcement and the increase of concrete strength, respectively.
