| 摘 要： | 在参考了其他学者在钢筋混凝土非线性有限元分析中所做工作的基础上,编制了完整的碳纤维布加固钢筋混凝土梁的非线性有限元分析程序.程序中采用了分离式有限元模型并且考虑了钢筋与混凝土之间粘结滑移关系.通过与试验梁对比,程序计算所得加固与未加固梁的极限承载力、梁的破坏形式、荷载-挠度曲线、加固层应变与试验值都很接近,验证了程序的可行性与适用性. |

| Abstract: | Basing on the achievements about the reinforced concrete non-linear finite element analysis,a program was written,which can be used to analyze CFRP strengthened reinforced concrete beam.A separate non-linear finite element model was proposed.The bonding and slipping between bar and concrete were concluded.Comparing to the experiment value including limit bearing capacity,type of beam destructing,load-deforming curve,strain of reinforced sheet,the effectiveness and applicability of the program was proved. |
| Keywords: | reinforced concrete beams CFRP non-linear finite element strengthen |
