（北京维拓时代建筑设计有限公司，北京 100025）[摘要] 呼市中银大厦是位于高烈度区的超高层建筑，采用框架-核心筒混合结构体系。本文通过对呼市中银大厦结构设计说明，介绍了该工程结构选型，地基基础设计特点及各阶段的抗震分析方法，重点阐述了高位桁架转换和防屈曲支撑设计思路。并详细讨论了型钢混凝土构件设计细节。可供同类结构设计时参考。[关键词] 超高层;混合结构;变刚度调平;高位桁架转换;异形型钢混凝土柱;防屈曲支撑中图分类号：TU973.1+7 文献标识码：A 文章编号：1002-848X(2013)S1-0110-05作者简介：冷冬梅，研究生，硕士，工程师，主任工程师，一级注册结构工程师，Email：lengdongmei@vtjz.com。Structural design of Huludao StadiumLeng Dongmei，Sun Huamin，Li Hui，Li Hongqiu(Beijing Victory Star Architecture & Civil Engineering Design Co., Ltd., Beijing 100025, China)Abstract: Huhhot Bank of China Building is the super high-rise buildings in High-intensity area by using frame-core wall system. Based on the structural design of Huhhot Bank of China Building,this paper elaborates the design features of the foundation and Performace-based seismic. high-level transfer truss and buckling-restrained-brace are mainly described. The member design of steel reinforced concrete columns is discussed in detail, which may be a reference to the similar projects.Keywords: super high-rise building; hybrid structure; optimized design of pile foundation stiffness to reduce differential settlement;high-level transfer truss;non-rectangular steel reinforced concrete columns;buckling-restrained-brace
