摘　　要：根据开孔板连接件的试验破坏形态,分析了孔中有无钢筋两种情况的开孔板连接件破坏机理.根据开孔板连接件的破坏机理,采用理论方法推导了开孔板连接件抗剪承载力的计算方法.通过与试验结果对比,证实本计算方法与其吻合较好,具有较高的精度,可被工程设计使用.According to the failure modes of perfobond rib connector, the failure mechanics of the connector with/ without penetrate reinforcement in the hole were carefully analyzed. Based on the failure mechanism of the connectors, the calculation method for computing the shear bearing capacity of perfobond connector was proposed by theoretical approaches. Compared with testing results, the calculation results well matches the test values, which indicates the new calculation method has adequate accuracy and it can be used in engineering design preceeding.
