| 摘 要： | 在碳纤维布对混凝土梁加固工程中,采用预应力技术可以充分发挥碳纤维布高强度的性能。针对碳纤维布在加固钢筋混凝土梁时性能不能充分发挥和在使用中加固效果不明显,对构件开裂荷载提高程度不大,难以抑制裂缝发展的问题,在试验研究的基础上,对预应力碳纤维布加固RC(钢筋混凝土)梁进行了截面应力分析,为其正截面抗弯承载力计算方法的建立提供了参考依据。 |
| 关 键 词： | 预应力 碳纤维布 应力分析 钢筋混凝土梁 |

| Abstract: | In the reinforcement of concrete beams using carbon fiber sheet,the prestressed technique can make full use of the high strength performance of carbon fiber sheet.In the light ofthe problems of weak reinforcement effect,less improvement of cracking load of reinforced and difficult controlling of crack development etc.in steel reinforcement concrete with carbon fiber sheet,based on experimental study,we analyzed the sectional stress of RC beams strengthened with prestressed carbon fiber sheet.The results can... |
