| 摘 要： | 为研究碳纤维增强复合材料(CFRP)加固钢筋混凝土梁的工作性能,利用大型有限元分析软件ANSYS,分别对钢筋混凝土梁、CFRP与钢筋混凝土梁之间的粘结性能以及CFRP单元进行有限元模拟;结合算例仿真分析了加固前后钢筋混凝土梁的承载力性能,初步探讨了CFRP布加固钢筋混凝土梁的剥离规律。结果表明,该仿真分析方法与工程实际符合较好,具有可行性和参考价值。

| Abstract: | To study the capacity of reinforced concrete beam strengthened with CFRP,the RC beam,the bond capacity between CFRP and RC beam and the element of CFRP were simulated by finite element analysis software ANSYS.The force-bearing capacity of the RC beam before and after strengthened with CFRP was discussed through an example,the rule of bonding removal between CFRP and RC beam was investigated initially.The results show that the simulation analysis method matches with the real engineering very well,and it is feasible for reference. |
