摘要
本文在试验研究的基础上,对带永久锚具的预应力芳纶纤维布加固混凝土梁的受弯承载力和刚度进行了分析,建立了其计算公式,给出了不同受力阶段的挠度计算方法。计算结果与试验结果符合较好,且计算偏于安全。
Based on tests, the analysis of flexural strength and stiffness of RC beams strengthened with prestressed aramid fiber reinforced polymer （AFRP） sheets with permanent anchor is carried out. The formulas for computing the load-carrying capacity and stiffness of the strengthening beams are derived. At the same time, the method of calculating deflection of the strengthening beams is proposed. The results from the formulas and those from experiment are in good agreement. And the calculating results show that the formulas are conservative.
