摘　　要：为了研究二次受力下的预应力碳纤维布加固钢筋混凝土梁抗弯性能研究及数值分析,对1根普通梁、1根直接粘贴预应力碳纤维布加固梁以及1根二次受力条件下的预应力碳纤维布加固钢筋混凝土梁进行抗弯性能试验研究,运用ANSYS有限元分析软件分别对以上情况进行模拟分析,并与试验结果相比较.通过对比来验证试验结果的可靠性,同时也为以后运用ANSYS有限元软件分析预应力碳纤维布加固钢筋混凝土梁提供参考.An ordinary RC beam,a RC beam strengthened by directly pasted prestressed CFRP,and a secondarily loaded prestressed CFRP beam were tested to compare their flexural behavior.Numerical analysis was carried out accordingly by using ANSYS finite element code and the simulation results were compared to the experimental results.By comparing the calculated results,the reliability of tests were verified.The study can also provide reference for future study using ANSYS finite element code on reinforced concrete beam with prestressed CFRP.
