摘要: 為更加深入和系統(tǒng)地了解高層建筑中應(yīng)用最廣的框架￣核心筒結(jié)構(gòu)，基于構(gòu)件的受力特點(diǎn)，首次提出了抗側(cè)組件的概念，指出核心筒、腹板框架和翼緣框架為該種結(jié)構(gòu)體系的三個(gè)主要抗側(cè)組件。 基于 6 棟普通框架￣核心筒結(jié)構(gòu)及衍生結(jié)構(gòu)體系的高層塔樓，計(jì)算了主要抗側(cè)組件所承擔(dān)的傾覆力矩比例來(lái)衡量其抗側(cè)能力，詳盡剖析了抗側(cè)組件的工作原理。 通過(guò)量化各抗側(cè)組件的抗側(cè)效能，使框架￣核心筒結(jié)構(gòu)的抗側(cè)體系設(shè)計(jì)更加明晰。 結(jié)果表明:在普通框架￣核心筒、筒中筒、帶環(huán)桁架的框架￣核心筒結(jié)構(gòu)中，核心筒為關(guān)鍵抗側(cè)組件；單獨(dú)帶巨撐或伸臂的框架￣核心筒結(jié)構(gòu)中，關(guān)鍵抗側(cè)組件分別是腹板框架和翼緣框架。

關(guān)鍵詞: 框架￣核心筒結(jié)構(gòu)； 抗側(cè)組件； 伸臂桁架； 巨型斜撐； 環(huán)桁架

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
