摘要:
在试验研究的基础上,结合纤维增强塑料筋混凝土梁的受弯破坏特点,探讨了纤维增强塑料筋混凝土梁的非线形全过程数值分析方法.通过对受压区和受拉区混凝土应力-应变关系曲线的简化,建立了纤维增强塑料筋混凝土梁弯距曲率的计算模式,提出了纤维增强塑料筋混凝土梁弯距曲率的简化计算公式以及相应的荷载挠度的计算公式.将该简化方法、非线性全过程数值分析方法与试验数据进行了比较分析,三者符合较好.
Abstract:
Based on experimental research, combined with the bending failure characteristics of fiber-reinforced plastic reinforced concrete beams, the numerical analysis method of the whole process of non-linear reinforced concrete beams of fiber-reinforced plastic reinforced concrete beams was discussed. By simplifying the stress-strain relationship curves of concrete in the compression zone and the tensile zone, the calculation mode of the curvature of the bending curve of the fiber-reinforced plastic reinforced concrete beam is established, and the simplified calculation formula of the curvature of the bending of the fiber-reinforced concrete beam and the corresponding load deflection are proposed. The simplified method, the nonlinear whole process numerical analysis method and the experimental data were compared and analyzed, and the three were in good agreement.
