摘　　要：通过有限元ABAQUS,研究了无粘结预应力CFRP筋混凝土梁的抗弯性能,并同试验数据进行了对比,结果表明,预应力CFRP筋混凝土梁的延性及受力性能较好,并与受拉区非预应力筋的配筋率有关。In order to analyze the flexural behavior of unbounded prestressed CFRP concrete beam,this paper carries out related infinite element ABAQUS,and compares the results with the experimental data. It is showed that the mechanical behavior and ductility of prestressed concrete beam with unbounded CFRP tendons are good. The reinforcement ratio of non-prestressed reinforcement in tensile region has a significant influence to the ultimate bearing capacity and ductility of these beams.
