摘　　要：通过使用有限元软件建立预应力芳纶纤维布加固钢筋混凝土梁的空间有限元模型,并与7根试件的受弯试验进行对比分析,试验结果表明,预应力芳纶纤维布加固的试验梁与未加固的基准梁相比,其开裂荷载提高了114%～306%,屈服荷载提高了38%～101%,极限荷载提高了29%～101%。可见,预应力芳纶纤维布能显著地提高被加固钢筋混凝土梁的抗弯性能。The finite element model for prestressed AFRP reinforced concrete was set up.Through compare analytical results with experimental results,while to compare the prestressed AFRP reinforced concrete beam with non-reinforced concrete beam,the cracking load increased by 114% to 306%,the yield load increased by 38% to 101%,and the ultimate load increased by 29%~101%.Obviously,prestressed AFRP cloth can significantly improve the flexural properties of reinforced concrete beams.
