【摘要】：随着建筑产业的不断发展,超高层建筑不断涌现,如何增加超高层结构的抗侧刚度、减小结构侧向位移已成为工程界关注的主要问题。近年来超高层结构体系广泛采用了中间核心筒与外围框架相结合的结构形式,通过设置伸臂桁架来协调核心筒与框架间的受力和变形。通过某项目介绍了伸臂桁架层转换箱形钢节点的施工方法及质量控制措施。
[Abstract]:With the continuous development of the construction industry, super-high-rise buildings are emerging, how to increase the lateral stiffness of super-high-rise structures, Reducing lateral displacement of structures has become a major concern in engineering circles. In recent years, super-tall structure systems have widely adopted the structure form of the combination of intermediate core tube and peripheral frame. This paper introduces the construction method and quality control measures of the transfer box steel joint of the extension arm truss by setting the arm extension truss to coordinate the force and deformation between the core tube and the frame.
