摘　　要：利用ANSYS对4根钢筋混凝土T型梁进行了有限元分析,研究碳纤维加固对T型梁抗弯性能的影响。结果表明,碳纤维加固能提高T型梁的屈服荷载和极限荷载;分析结果与试验结果吻合较好,表明通过选取合适的单元和设定合理的参数,利用ANSYS对碳纤维加固T型梁进行有限元分析是一种有效的方法。The finite element models of 4 reinforced concrete T-beams have been made by using ANSYS to analyze the influence of CFRP reinforcement on the flexural properties of T-beams.The results show that the yield load and ultimate load of T-beams have been improved with CFRP reinforcing;the nonlinear analysis results using finite element method match well with the experimental data,so it＇s an effective way to conduct finite element analysis on T-beam reinforced with CFRP by using ANSYS.
