| 摘 要： | 对粘贴碳纤维布加固的钢筋混凝土梁进行了正截面受弯承载力分析。分析表明，碳纤维布可以显著提高梁的正截面受弯承载力。总体上，二次受力对钢筋混凝土加固梁影响不大，但是会从一定程度上降低其加固效果。本文可以为钢筋混凝土受弯构件加固设计提供一些参考。

| Abstract: | Reinforced concrete(RC) beams strengthened in flexure with carbon fiber reinforced polymer(CFRP) laminates considering the secondary loading were studied in the paper.The results indicate that the CFRP laminate could considerably increase the flexural bearing capacity of RC beams.As a whole,the secondary loading affects the ultimate flexural bearing capacity a little,but the stress at the first stage could reduce the strengthening effect to some extent.The achievements can be referenced for the strengthening design of RC flexural elements. |
