CFRP板嵌贴加固混凝土粘结滑移数值分析

摘要

Take the finite element analysis of the CFRP plate-concrete drawing experiments as an example, to introduce the application of the ANSYS finite element software Combine39 unit slip analysis. Mixed carbon fiber with concrete to build the finite element analysis model of drawing experiments, combining the relevant mechanical analysis, to obtained anchorage length and the slippage result from the CFRP plate and concrete, and then campared with the experimental data. The results showed that the experimental results are consistent with the theoretical value, that ANSYS software can be easily used to analyze slid between CFRP and concrete.%以CFRP板一混凝土的拉拔实验的有限元分析为例，介绍了ANSYS有限元软件中的Combine39单元在滑移分析中的应用，建立碳纤维板与混凝土的拉拔实验的有限元分析模型，进行了相关力学分析，求出CFRP板在混凝土中的滑移量，并与实验中的相关数据作比较。结果表明，实验结果与理论值相吻合，证明ANSYS软件能方便地用于CFRP与混凝土间的滑移分析。
