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。
The changes of the bearing capacity and failure mode of the reinforced concrete columns reinforced with carbon fiber sheets reinforced with different bonding methods and numbers of layers are analyzed. The experimental results show that the carbon fiber cloth has a good reinforcing and reinforcing effect on the carrying capacity of reinforced concrete columns. On this basis, a simplified formula for calculating the normal section bearing capacity of reinforced concrete columns strengthened by carbon fiber sheets is proposed, which is in good agreement with the experimental results.
