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。

Abstract: In order to have a more in￣depth and systematic understanding of the most widely used frame￣core tube structurein high￣rise buildings， based on the force characteristics of the components， the concept of anti￣lateral components wasproposed for the first time. It was pointed out that the core tube， the web frame and the flange frame were the three mainanti￣lateral components of this kind of structural system. Based on 6 high￣rise towers with common frame￣core tube structureand derivative structural system， the ratio of overturning moment assumed by the main anti￣lateral components wascalculated to measure anti￣lateral capacity， and the working principle of anti￣lateral components was analyzed in detail. Byquantifying the anti￣lateral efficiency of each anti￣lateral component， the design of the anti￣lateral system of the frame￣coretube structure was more clear. The results show that in the common frame￣core tube， tube￣in￣tube， frame￣core tubestructure with ring truss， the core tube is the key anti￣lateral component. In a frame￣core tube structure with a single giantdiagonal 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
