摘　　要：提出一种便于工业化建造的装配式钢-混凝土组合框架结构系统,从结构构件、构造和构成角度,阐述其所采用的预制构件类型、特点及相应节点连接方式。提出一种便于组合结构快速建造的新型梁柱连接节点。该节点采用干式连接,对其组成、构造和理论计算方法进行介绍,通过ABAQUS有限元软件对该节点的受力性能、屈服模式进行数值分析。结果表明,理论计算方法与数值分析结果误差在10%以内,验证节点构造方式和所提理论计算方法的合理性、可行性。总结工程项目应用装配式钢-混凝土组合结构的设计方法及确保工程品质的技术控制要点。This paper proposes a prefabricated steel-concrete composite frame structure system which is convenient for industrial construction. From the perspective of structural components,structure and composition,the types,characteristics and corresponding joint connection methods of prefabricated components are described. In this paper,a new type of beam-column joint is proposed,which is convenient for the rapid construction of composite structures. The dry connection is adopted in the joint,and its composition, structure and theoretical calculation method are introduced. The mechanical performance and yield mode of the joint are analyzed by ABAQUS finite element software. The results show that the error between the theoretical calculation method and the numerical analysis results is less than 10%,which verifies the rationality and feasibility of the joint construction method and the theoretical calculation method. This paper summarizes the design method of prefabricated steel-concrete composite structure and the key points of technical control to ensure the quality of the project.
