摘要:
根据纤维增强塑料筋(FRP筋)及其混凝土梁的力学性能,建立了纤维增强塑料筋混凝土梁达到纤维增强塑料筋名义屈服强度的截面曲率和梁最终破坏的截面曲率的表达式.以此为基础,探讨了纤维增强塑料筋混凝土梁截面曲率延性的计算方法.结果表明,纤维增强塑料筋混凝土梁截面曲率延性系数分别随纤维增强塑料筋配筋率的减小和混凝土强度的提高而增大.
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.
