为研究在钢-轻骨料混凝土组合梁和组合板结构中所使用的开孔钢板连接件的抗剪承载能力和剪切刚度等受力性能,采用了推出试验方法,完成了6个采用轻骨料混凝土的开孔钢板连接件推出试件的试验研究,在试验研究中着重考察了开孔钢板连接件的孔洞直径和开孔钢板连接件端部承压方式对剪切连接件受力性能的影响.试验研究结果表明:(1)总体表现为端部承压构件极限承载能力远高于端部不承压构件,因为在端部承压构件中,开孔钢板连接件受到端部混凝土阻挡,因而其极限承载能力相埘较高;(2)开孔钢板连接件中孔洞直径对开孔钢板抗剪强度有明显影响,孔洞直径越大,极限承载力也越大;(3)开孔钢板连接件具有很高的抗剪强度和刚度,具有较好推广应用价值.

To study the shearing capacity and shearing rigidity of perfobond connector that used in steel-lightweight aggregate concrete composite beams and composite slab structures, experimental researches on six perfobond connector specimens of lightweight aggregate concrete have been conducted with Push-out test. The experimental researches focus on the influences of the end bearing and diameter of perfobond connector on the mechanical behavior of the shear connector. The analysis results show that: firstly, the ultimate capacity of the end beating perfobond connector specimens is much higher than those without end bearing, because perfobond connectors are subjected to the end concrete block ; secondly, the diameter of perfobond connector has significant effect on the shearing capacity of perfobond connector and the larger diameter of the holes, the higher the ultimate bearing capacity is; lastly, the perfobond connect has comparative high shearing capacity and sheafing rigidity and is available for wider applications.
