摘要
为摸清碳纤维片材加固混凝土梁中粘接界面上的应力分布,本文利用ANSYS商业软件进行了有限元分析。重点研究了有限元计算模型、碳纤维片材层数以及U形箍对粘接界面应力的影响。研究结果表明,有限元计算模型、碳纤维片材层数对粘接界面端部的应力峰值有影响,U形箍会改变粘接界面上的应力分布。
For understanding the interfacial stresses' distributing of the strengthened RC beams externally bonded with CFRP systems,the FEM analysis is carried out with ANSYS in this paper.The effects of the FEM model,the layer sum of CFRP and the U shape hoop to the interfacial stresses are emphatically studied.The analysis results indicate that the FEM model and the layer sum of the CFRP can affect the peak value of the interfacial stresses.The U shape hoop will change the distributing of the interfacial stresses.
