碳纤维布增强钢筋混凝土柱正截面承载能力的试验研究

Research on the Flexural Strength of RC Columns Strengthened with Continuous CFS

分析了采用不同粘贴方式和粘贴层数的碳纤维布补强加固的钢筋混凝土柱在正截面承载力和破坏形态等方面的变化情况。试验研究表明 :碳纤维布对钢筋混凝土柱的承载能力具有良好的补强加固效果。在此基础上 ,提出了碳纤维布加固钢筋混凝土柱正截面承载力的简化计算公式 ,它与试验结果能较好地吻合。

Based on the experimental study of three groups of reinforced concrete columns subject to axial compression and bending,this paper analyzes the effect of using continuous carbon fiber sheet for reinforcing the flexural strength and failure mode of these specimens.The results indicate that the carbon fiber sheet could effectively increase the flexural strength of reinforced concrete columns.And then,according to the study mentioned above,the paper proposes the simplified design formulas to calculate the flexural strength of reinforced concrete columns by using continuous carbon fiber sheet.The results of the calculation and the experiment coincide well.
