| 摘 要： | 在GFRP布加固钢筋混凝土梁受弯试验的基础上,考虑钢筋、混凝土的材料非线性行为,采用有限元法对FRP加固钢筋混凝土梁的受弯力学性能进行了数值模拟和分析,并与试验结果进行了比较.根据计算结果,分析了FRP加固钢筋混凝土梁的极限荷载、剥离荷载、FRP的应变分布、FRP端部区应力分布情况及受力机理.分析结果表明,非线性有限元法可以很好地模拟FRP加固钢筋混凝土梁的受力性能,并能预测FRP加固钢筋混凝土梁发生剥离破坏的荷载. |

| Abstract: | Based on the experimental tests of RC beams strengthened with GFRP(glass fiber reinforce polymer) sheets,the flexural behavior of RC beams strengthened with GFRP sheets is numerically simulated and analyzed using finite element method(FEM).The nonlinear behavior of concrete and steel is considered in the analysis.The ultimate loads,debonding loads,distribution of FRP sheets are also analyzed.The analytical results show a good agreement with the experimental results.The flexural behavior of RC beams can be simulated effectively with FME method. |
