| 摘 要： | 碳纤维布加固混凝土结构是一种新型结构加固方法。本文进行了６个碳纤维布加固混凝土柱和一个对比混凝土柱的受剪试验研究，分析了碳纤维布的受剪加固机理及其影响碳纤维布受剪加固效果的因素。试验研究表明，碳纤维布受剪系数ν与碳纤维配箍特征值λ_（ＣＦＳ）、剪跨比和轴压比等因素有关。根据试验结果分析，提出了碳纤维布受剪系数ν的计算方法和碳纤维布加固混凝土柱受剪承载力计算公式，计算值与试验值吻合较好。

| Abstract: | Concrete structure strengthened with carbon fiber reinforced plastic sheet (CFS) is a new retrofit method in the field of civil engineering. In this paper, six columns have been tested under different shear-span ratios and axial compression ratios with different amounts of CFS, and a concrete column has been tested for comparison. Based on experimental results, the shear coefficient (v) of CFS has been studied with a calculation formula proposed for coefficient (v) depending on shear-span ratio, axial load ratio and CFS amount. Comparing with experimental data, the calculated results show good agreement. |
