| 摘 要： | 主要讨论了考虑二次受力情况下碳纤维布加固RC梁正截面受力分析，通过理论计算得出了有初始荷载存在情况下CFRP布加固RC梁的破坏荷载，通过对比三根梁，得出二次受力情况下预应力CFRP布加固RC梁受力性能有了很大的提高。

| Abstract: | The normal section force analysis of RC beam strengthened by CFRP under secondary loading is discussed,the failure load of RC beam strengthened by CFRP on the premise of the existing of initial load is got through theoretical calculation.Through the contrast between three beams gets the conclusion that the load capacity of RC beam strengthened by prestressed CFRP is greatly improved under secondary loading. |
