摘　　要：开孔板和开孔波折板是钢-混凝土组合结构中的两种新型抗剪连接件。分别设计、制作了不同构造参数的开孔板和开孔波折板连接件剪切试件,完成了对比加载试验。研究了两种新型连接件剪切试件的破坏形态、荷载-滑移特性及相同构造参数下两种连接件的抗剪承载能力。研究结果表明:两种连接件均发生纵向劈裂破坏;开孔板连接件无明显的塑性滑移特性,开孔波折板连接件有明显的塑性滑移特性;波折面的局部承压对开孔波折板连接件的抗剪能力有较大影响;相同构造参数下,开孔波折板连接件的承载力约为开孔板的3倍。The perforated plate and the corrugated perforated plate are two new types connectors in steel-concrete composite structures.The shear samples of the perfobond plate connectors and corrugated perforated plate connectors,which have different structure parameters,are designed,and the contrast load tests are accomplished.The failure modes,the characteristics of load-slip and the shear bearing capacity of two types connectors that have same structure parameters are studied.The conclusions show that the failure modes of two types connectors are vertical fracturing,the perforated plate connectors have no obvious plastic slip characteristics,which are opposite to corrugated perforated plate connectors;the local pressure of twists and turns surface has a great influence on shearing capacity of the corrugated perforated plate connectors;under the same structure parameters,the bearing capacity of corrugated perforated plate connectors is about three times perforated plate connectors.
