摘　　要：采用有限元方法对CFRP加固二次受力钢筋混凝土梁的抗弯性能进行了分析,并与试验结果进行了比较。结果表明,通过合理选择有限元分析数值模型,可以较好地预测CFRP加固钢筋混凝土梁的抗弯性能。试验研究与有限元理论分析比较,结果比较吻合,表明本文提出的数值模拟研究的理论及方法是可行的,可以用于工程设计计算和作为模型试验的参考。Finite element program ANSYS was used to research the reinforced concrete beams strengthened with CFRP, and the results was compared with experiment. The analyzed results indicated that according to choose numerical simulation, it can forecast the bending behavior of the concrete beams strengthened with CFRP. Experimental results show in good agreement with finite element analysis ones. It means that the analyzing methods proposed in this paper are reasonable, which can be referred for construction design and model experiment.
