发布时间：2018-08-26 15:54
【摘要】：预制钢管混凝土剪力墙是一种新型钢-混凝土组合剪力墙结构体系，即以钢管混凝土柱作为暗柱或边框，与剪力墙共同作用组成的全预制抗侧力结构体系。受力合理的节点、接缝设计是该结构体系设计的关键技术，也是决定该结构形式能否推广应用的重要因素。文中以钢管混凝土边框与剪力墙竖向结合面连接设计为研究对象，结合面连接方式分为两种：栓钉和销键组合连接、连接筋和销键组合连接。通过试验和理论分析研究钢管混凝土边框与剪力墙竖向结合面的抗剪承载力。 为研究采用栓钉和销键的连接方式进行连接时结合面的连接性能，试验设计了5个钢管混凝土边框与剪力墙竖向结合面试件。分析各试件的破坏特征和极限承载力，试验结果表明：栓钉和销键的组合连接方式能够保证结合面剪力的传递，且具有较好的抗剪承载力和延性，能够使结合面进行可靠连接。为研究采用连接筋和销键的连接方式进行连接时结合面的连接性能和抗震性能，试验设计了24个钢管混凝土边框与剪力墙竖向结合面试件。该组试件用水平钢筋代替栓钉，钢筋穿过钢管，并利用碳纤维布对试件进行不同程度的加固处理以有效测试结合面抗剪承载力及抗震性能。对试件破坏形态、滞回特性和延性等性能进行分析，结果表明：该连接筋和销键的组合连接方式具有良好的刚度、延性及抗震性能。 在试验研究基础上，提出钢管混凝土边框与剪力墙竖向结合面设计建议：采用栓钉（或水平钢筋）和销键组合连接方式具有良好的抗剪承载力和延性，可用于工程实际中，但在钢管混凝土边框与剪力墙结构设计中，建议采用水平筋和销键的组合连接方式。
[Abstract]:Precast concrete filled steel tubular shear wall (CFST) is a new type of steel-concrete composite shear wall structure system. Joint design is the key technology of the structural system design, and it is also an important factor to decide whether the structure form can be popularized and applied. In this paper, the connection design of concrete filled steel tube (CFST) frame and shear wall vertical joint surface is studied. There are two kinds of connection modes: the combination of bolt and pin key, and the combination of connecting reinforcement and pin key. The shear bearing capacity of concrete filled steel tube (CFST) frame and shear wall is studied by experiment and theoretical analysis. In order to study the connection performance of the joint surface with the connection between pin and pin, five concrete filled steel tube (CFST) frames and shear walls were designed for vertical connection interview. The failure characteristics and ultimate bearing capacity of each specimen are analyzed. The test results show that the combined connection mode of pin and pin bond can ensure the shear force transfer of the bonding plane, and it has good shear bearing capacity and ductility, and can make the joint face be connected reliably. In order to study the connection performance and seismic behavior of the interface when connecting the steel bar and the pin key, 24 concrete filled steel tube (CFST) frame and shear wall vertical joint interview pieces were designed. In this group of specimens, horizontal steel bar is used instead of bolt, and steel bar passes through steel pipe, and carbon fiber sheet is used to reinforce the specimen in varying degrees to effectively test the shear capacity and seismic behavior of the joint. The failure morphology, hysteretic characteristics and ductility of the specimens are analyzed. The results show that the combined connection of the steel bar and the pin bond has good stiffness, ductility and seismic performance. On the basis of experimental study, the paper puts forward the design suggestion of vertical joint plane of CFST frame and shear wall: the combination of bolt (or horizontal steel bar) and pin bond has good shear bearing capacity and ductility, and can be used in engineering practice. However, in the structure design of CFST frame and shear wall, the combination of horizontal reinforcement and pin key is suggested.
