摘　　要：为了研究开孔钢板连接件在梁桁体系钢-混组合梁中的连接性能,通过粘贴应变片和架设位移计测得组合梁跨中截面应力和滑移,分析开孔钢板连接件对组合梁性能的影响。研究表明:开孔钢板连接件使得混凝土与钢桁架交接面的相对滑移量极小,组合梁跨中截面基本符合平截面假定,具有较优的连接性能。In order to study the connection performance of the perforated plate connectors in the composite beam with hybrid full web and truss system, the cross／｜section stress and slip of the composite beam is measured by pasting a strain gauge and erecting a displacement meter in this test. Meanwhile, the influence of the perforated plate connectors on the performance of the composite beam is analyzed. The study shows that the relative slippage of the interface between concrete and steel truss will be quite small with the perforated plate connectors, and the midspan of the composite beam basically meets the flat section assumption. Besides, excellent connection performance can be observed.
