摘　　要：采用试验和有限元软件ANSYS仿真分析相结合的方法,分析CFRP布加固梁的承载能力、变形特性、破坏形式和CFRP布加固混凝土结构的承载机理.研究表明:外贴CFRP布加固不仅可有效地提高RC梁的承载能力和刚度,而且可以大幅度地提高其安全储备,加固梁的承载力随着粘贴的CFRP层数的增加而增长,但加固1层是最经济,效果最好的.The bearing capacity, deflection characteristics, failure mode and bearing mechanism of RC structures reinforced with CFRP sheet were analyzed by use of beam test and simulation analysis with ANSYS software. The results indicated that adoption of CFRP sheet could effectively improve not only the bearing capacity and stiffness but also the safety margin of RC beams. The bearing capacity of RC beams increased with the number of layers of CFRP sheets. The most economical and effective way was using single layer of CFRP sheet.
