| 摘 要： | 粘贴碳纤维布加固混凝土梁粘贴界面的长期性能,特别是承受长期荷载后的抗疲劳性能是这种加固方法能否推广应用的关键问题,基于此对碳纤维布加固钢筋混凝土梁徐变后的疲劳性能进行了试验研究.研究结果表明:粘贴碳纤维布的钢筋混凝土梁具有良好的疲劳性能,经过相同次数的疲劳荷载后,没有经历徐变过程的加固梁与未加固梁相比,前者的挠度比后者... |

| Abstract: | The long-term behavior of bonding surface of concrete beams reinforced with carbon fiber sheets,especially,the fatigue behavior under long-term load is the key factor for its successful use.The experimental investigation was conducted about the fatigue behavior of reinforced concrete beams strengthened with carbon fiber sheets after creep.It is shown that the reinforced concrete beams strengthened with carbon fiber sheets have better fatigue behavior.The deflection of strengthened beams which had not crept ... |
