摘要
采用非线性有限元分析软件ABAQUS对未加固连续梁、侧贴碳纤维布加固连续梁进行数值模拟,并将有限元分析结果与试验结果对比。分析表明:与未加固连续梁相比,侧贴碳纤维布加固连续梁的承载力和变形性能明显提高,提高的幅度随碳纤维布侧贴高度增大而降低;基于ABAQUS的有限元分析结果与试验分析结果吻合较好,可在一定程度上有效替代试验分析方法,从而减少试验所需的时间和费用,可以为类似的加固设计和试验提供参考。
Numerical simulation by the nonlinear finite element analysis software ABAQUS were done for the non-strengthened continuous beam and the continuous beams strengthened with side bonded CFRP sheets. The results of finite element analysis were compared with test results. The test results show that ： compared with the non-strengthened continuous beam, the bearing capacity and the fiexural performance of the contin- uous beams strengthened with side bonded CFRP sheets obviously improve, and the rate of increase of CFRP sheets with side height increases. The finite element analysis results based on ABAQUS and the experimental results are in good agreement. So, finite element analysis method is feasible and available in practical application, which can greatly reduce labor cost and other costs compared with experimental analysis method and can provide reference for similar reinforcement design and research,
