摘　　要：本文采用条带分析法 ,对CFRP加固的承受异号弯矩的钢筋混凝土梁截面的极限承载力进行了分析 ,探讨了截面可能的破坏和期望的破坏形式 ,并通过算例比较了不同加固方案对截面极限承载能力的影响。In this paper the load-bearing capacity of RC beam ,bearing contrary sign moment strengthened with CFRP, was analyzed by means of strip analysis method. The possible and expected destruction forms of beam section were discussed. The influence on the load-bearing capacity of different strengthening schemes was compared Based on it,the shortcut computing method of the load bearing capacity of the normal section and strengthening design requirements were proposed.
