| 摘 要： | 通过对3根碳纤维布加固小偏压钢筋混凝土柱及对比柱的静载试验和理论分析，表明采用横向缠绕碳纤维布加固后小偏压柱的极限承载力有不同程度的提高，变形能力得到改善。横向碳纤维约束了混凝土的变形，提高了混凝土的极限抗压强度。提出了碳纤维加固小偏压柱的承载力计算公式和设计建议。

| Abstract: | Three reinforced concrete beam-columns strengthened with carbon fiber reinforced polymer(CFRP) and contrast sample are tested under static load,the theory models are analyzed.The strength capacity and ductility of beam-columns wrapped with transverse CFRP under a small load eccentricity improved significantly.CFRP has good effect on confining the deformability of concrete and enhancing the compressive ultimate strength of concrete.The calculating formula and design advice are presented. |

| Keywords: | CFRP strengthening beam-column confined concrete ultimate capacity |
