（奥雅纳工程顾问，深圳 518048）［摘要］超高层总部塔楼建筑总高度为400m，采用密柱框架-核心筒结构体系，不设结构加强层，与传统的超高层框架-核心筒结构二道防线抗震设计不同，对本工程采用内外结构整体共同协调作用的抗震理念进行体系论证和设计，并针对结构设计中抗震设计的主要关键部分，如剪力墙的拉剪设计、梁柱偏心节点、核心筒斜墙收进等进行了深入的设计研究，从而确保整体结构设计的安全可靠和经济合理。［关键词］密柱框架-核心筒; 剪力墙拉剪; 梁柱偏心节点; 核心筒斜墙收进; 共同作用中图分类号：TU318 文献标识码：A 文章编号：1002-848X(2014)24-0031-06Research on structural system and key issues design of a super-tall buildingLin Hai, Richard Lee, Kang Man, Lin Fengjun, Wang Yang, Mu Jichang, Zhen Shengwei, He Zixuan(Arup, Shenzhen 518048, China)Abstract: As a 400 meter high building, the structural system of this headquarter building is close column frame and core wall system without strengthened stories. Different from dual-defenses seismic design of traditional super-tall frame and core wall system, this structural system induced seismic concept of integrated work for external and internal structures to analyze and design. Key parts in seismic design were deeply studied, such as tension and shear design of shear wall, beam-column eccentric connection and setback of inclined shear walls, which ensured the safety and economy of the building.Keywords: close column frame and core wall system; tension and shear of shear wall; beamcolumn eccentric connection; setback of inclined shear walls of core; integrated work作者简介：林海，硕士，一级注册结构工程师，Email:hai.lin@arup.com。参考文献［1］奥雅纳工程顾问. 华润深圳湾综合发展项目华润总部塔楼超限审查报告［R］. 深圳, 2012.［2］JGJ 3—2010 高层建筑混凝土结构技术规程［S］. 北京:中国建筑工业出版社,2011.［3］GB 50011—2010 建筑抗震设计规范［S］. 北京:中国建筑工业出版社,2010.［4］Keyword user′s manual volume Ⅰ & Ⅱ ［M］.California: Livermore Software Technology Corporation, 2012.［5］抗剪强度专题研究组.钢筋混凝土偏心受压和偏心受拉构件的抗剪强度［J］. 建筑结构学报,1982,3(5):1-10.［6］SJG 18—2009预制装配整体式钢筋混凝土结构技术规程［S］. 北京:中国建筑工业出版社,2009.［7］周蓓蕾，穆继昌，江民，等.某总部塔楼梁柱偏心钢节点研究［Ｊ］．建筑结构，2014，44（24）：116-121.
