基于钢板加固和碳纤维布加固完好状态下和正常使用极限损伤状态下的受弯构件的破坏荷载试验，研究钢筋混凝土受弯构件在采用粘贴钢板加固和粘贴碳纤维布加固措施后，其挠度、裂缝及应变等的发展变化规律。对比分析完好状态下和正常使用极限损伤状态下采用不同的加固方式，受弯构件极限承载力提高幅度的差异并将受弯构件的其他力学控制指标进行对比分析，综合检验评定其加固效果。试验结果表明：两种加固措施对提高在不同损伤状态下的钢筋混凝土受弯构件的抗弯承载力都具有显著效果，但完好情况下的加固效果优于受损情况，钢板加固措施优于碳纤维布加固。

Based on the destructive load experiment of the flexural members by steel plate and carbon fiber sheet in sound state and normal service limit damaged state,the deflection,crack and strain development status and changes of the flexural members reinforced by steel plate and carbon fiber sheet were studied. Comparing the difference of the bending bearing limit capacity,and other indicators with flexural members each other by different way of strengthening in sound state and normal service limit damaged state,evaluating the reinforcement effect comprehensively,the results show as follows. Two kinds of reinforcement measures have significant effect in improving the flexural capacity of the reinforced concrete flexural members in different damaged states. But the effect in sound state is superior to that in damaged state. The effect of the reinforcement by steel plate is superior to that by carbon fiber sheet.
