摘　　要：钢-混凝土组合结构是一种使用剪力连接件将钢材与混凝土两种材料连接在一起的达到共同受力的结构体系,此结构综合了两种材料的力学性能优势。为研究高强楼面板-轻钢梁界面抗剪键连接性能与破坏形态,通过推出试验研究由单向紧固螺栓对超高性能混凝土和钢梁进行抗剪连接的承载力和破坏形态。对三组试件的荷载滑移曲线和破坏形态进行分析,在螺栓破坏形式、钢材破坏程度和混凝土破坏程度等方面进行逐一对比分析。对高强楼面板-轻钢梁抗界面剪键连接性能与破坏形态进行总结,并提出设计和使用建议。Steel-concrete composite structure is a kind of structural system that uses shear connectors to connect two materials,steel and concrete,to achieve common force,and this structure combines the advantages of the mechanical properties of the two materials.In order to study the high-strength floor panels-light steel beams to resist the interface shear bond connection performance and damage morphology.The group designed a total of three groups of components,through the launch of the test to study the unidirectional fastening bolts on the ultra-high performance concrete and steel beam shear connection of the bearing capacity and damage patterns.The load-slip curves and damage patterns of the three groups of specimens were analysed,and comparative analyses were carried out one by one in terms of the bolt damage form,the degree of steel damage and the degree of concrete damage.The performance and damage pattern of the interface shear bond connection of high-strength floor panels-light steel beams are summarised,and design and use recommendations are made.
