利用ANSYS建立14根碳纤维布加固钢筋混凝土简支梁模型，分析在两种配筋率情况下，不同初始荷载对钢筋混凝土梁碳纤维布抗弯加固效果的影响。结果表明：碳纤维布加固可显著提高梁的屈服荷载和极限荷载，梁的屈服荷载和极限荷载的提高幅度随着初始荷载的增加而减小；配筋率越小，受拉钢筋利用越充分，梁的极限荷载提高幅度越明显。

Fourteen reinforced concrete simply supported beam models with CFRP sheets were built by using ANSYS, and the influence of different initial loads on the reinforcement and flexural strength effects of CFRP sheets in two steel rein-forcement ratios was analyzed. The results indicated that reinforced carbon fiber sheet could significantly increase the yield-ing load and ultimate load of the beam. The enhancement of yielding load and ultimate load decreased with the increase of initial load. The more adequate the steel reinforcement utilization rate was, the more significantly the ultimate load with small reinforcement ratio would be improved.
