| 摘 要： | 根据碳纤维薄板增强钢筋混凝土三点弯曲梁随着纤维薄板粘贴长度的增大出现三种典型的破坏形式,建立了增强梁的抗弯力学分析模型,提出了不同破坏形式时增强梁承载力的理论计算方法.将承载力计算值与试验值进行对比,结果表明,增强梁承载力计算方法是可行的.

| Abstract: | By taking reinforced concrete beams strengthened with carbon fiber sheet under the 3-point bending conditions as the objects, the three typical failure modes occur as the increasing length of carbon fiber sheet. The mechanical model of flexural behavior for reinforced concrete beams strengthened with carbon fiber sheet is set up, and the appropriate formulas about the ultimate load bearing capacity are presented under different failure modes.The calculating results of load bearing capacity are compared with the experimental results. It is shown that the formulas are right. |
