摘要:为更加深入和系统地了解高层建筑中应用最广的框架-核心筒结构,基于构件的受力特点,首次提出了抗侧组件的概念,指出核心筒、腹板框架和翼缘框架为该种结构体系的三个主要抗侧组件。基于6栋普通框架-核心筒结构及衍生结构体系的高层塔楼,计算了主要抗侧组件所承担的倾覆力矩比例来衡量其抗侧能力,详尽剖析了抗侧组件的工作原理。通过量化各抗侧组件的抗侧效能,使框架-核心筒结构的抗侧体系设计更加明晰。结果表明:在普通框架-核心筒、筒中筒、带环桁架的框架-核心筒结构中,核心筒为关键抗侧组件;单独带巨撑或伸臂的框架-核心筒结构中,关键抗侧组件分别是腹板框架和翼缘框架。
关键词:框架-核心筒结构,抗侧组件,伸臂桁架,巨型斜撑,环桁架

Abstract: In order to have a more in-depth and systematic understanding of the most widely used frame-core tube structure in high-rise buildings, based on the force characteristics of the components, the concept of anti-lateral components was proposed for the first time. It was pointed out that the core tube, the web frame and the flange frame were the three main anti-lateral components of this kind of structural system. Based on 6 high-rise towers with common frame-core tube structure and derivative structural system, the ratio of overturning moment assumed by the main anti-lateral components was calculated to measure anti-lateral capacity, and the working principle of anti-lateral components was analyzed in detail. By quantifying the anti-lateral efficiency of each anti-lateral component, the design of the anti-lateral system of the frame-core tube structure was more clear. The results show that in the common frame-core tube, tube-in-tube, frame-core tube structure with ring truss, the core tube is the key anti-lateral component. In a frame-core tube structure with a single giant diagonal brace or outrigger, the key anti-lateral components are the web frame and the flange frame.
Keywords: frame-core tube structure; anti-lateral component; outrigger truss; giant diagonal brace; ring truss
