| 摘 要： | 利用碳纤维布加固钢筋混凝土构件以提高承载能力及延长寿命是目前比较流行的方法。本文采用分离式有限元模型分析了碳纤维布加固钢筋混凝土构件裂缝及界面处的应力状态，并对其承载能力的提高性能进行了机理分析和推算。分析结果表明，碳纤维布使得构件在裂缝处的应力分布更加趋于平缓、应力减小，且承载能力及刚度随着配筋率的不同均有不同程度的提高。

| Abstract: | The reinforced concrete members improved with continuous carbon fiber is a prevalent way to raise its load bearing capacity and extend life. In this paper, a FEM is used to analyze the behavior mechanism of stress field in interface and cracks . Also load bearing capacity is calculated. The results show that carbon fiber can raise the carrying capacity and cause the stress reduced. |
