膨胀螺栓外锚半钢管加固梁负弯矩区的试验研究

摘要

The test used the implant expansion bolt anchor half pipe technology to achieve carbon fiber reinforced frame beam negative moment area of purpose. Providing a new reinforcement technology that uses half pipe to anchor CFRP at the negative moment of the beam position for node reinforcement. To verify the efficiency of the strengthening methods, five frame joints have been tested under static loading test and analyzed with the ANSYS non-linear finite element analysis software. The test and analysis results show that by the strengthening way of this paper the ultimate load of the five specimens are increased.%试验采用内植膨胀螺栓外锚半钢管技术来达到碳纤维布加固框架节点梁负弯矩区的目的.提出利用半钢管对负弯矩区加固的碳纤维布进行锚固的一种新技术.通过对5个框架节点的静力加载试验,以及用非线性软件ANSYS进行模拟分析,验证了本文采用的加固方法可行.试验及分析结果表明,本文采用的加固方法加固效果明显,能有效提高试件的承载力.
