［摘要］对不同加载方式和不同加固模式下的碳纤维增强复合材料(CFRP)加固H型钢梁进行了两组比较试验，并对试验结果进行了综合分析。通过对试验结果的比较分析，给出了各种加固方式下的钢梁的极限承载力变化及CFRP布和钢梁的各项力学性能，得出了一些具有工程指导意义的结论。

Abstract:Experiments of H\|shaped steel beams bonded with CFRP in different loading conditions and different reinforced methods  were compared. Ultimate bearing capacity and  mechanical properties of speciments were concluded  from comparing test and analysis results.  Some useful conclusions in engineering applications were also presented.
Keywords:CFRP； strengthening； H\|shaped steel  beam； static experiment
