Experiment on Shear Transferring Mechanics of Perfobond Rib Connector

摘要:

提出新的开孔板连接件抗剪承载力测试方法.共进行七组21个试件试验，测试开孔板连接件的荷载滑移关系，观测开孔板连接件的破坏形态.结果表明：每组试件的荷载滑移曲线重复性较好，验证了本文提出的测试方法的合理性.根据试验结果，分析开孔板连接件的破坏性质及影响开孔板连接件抗剪承载力的因素.

Abstract:

A new push out test method for perfobond rib connector was proposed and 7 different groups, totally 21, push out testing specimens were carried out. The load relative slip relationships of the specimens were tested and their failure modes were observed. The testing results show good reproducibility of load relative slip curve in each group, which proves the rationality of the proposed testing method. The failure property for the perfobond connector and influence factor for its shear bearing capacity are analyzed.
