（北京市建筑设计研究院有限公司， 北京 100045）［摘要］西安航天城文化生态园揽月阁为纯钢结构的塔式建筑，总高度为110.7m。对三种结构方案进行比较，最终采用钢框架-中心支撑结构，内筒采用钢支撑体系，外围为钢框架体系，只在建筑的四个角部设置框架柱，形成跨度为30m的框架梁。采用素土挤密桩进行湿陷性黄土地基处理，采用埋入式柱脚与基础承台内设置暗钢梁相结合的方式处理柱脚。采用钢筋混凝土框架骨架形成了较大高度的砌筑墙。工程设计完美地实现了建筑意图。［关键词］塔式建筑; 钢结构; 钢框架-中心支撑结构; 节点设计中图分类号：TU391 文献标识码：A 文章编号：1002-848X(2014)20-0038-05Structural design of Embraced-moon Tower of Cultural and Ecological Park in Astronautics Industrial Centre in Xi′anChen Lin, Shu Weinong（Beijing Institute of Architectural Design, Beijing 100045, China）Abstract: Embraced-moon Tower of Cultural and Ecological Park in Astronautics Industrial Centre in Xi′an is a pure steel structure tower architecture with the total height of 110.7meters. The concentrically braced steel frame structure was adopted by comparison of three structure schemes. The core tube of the structure is steel braced structural system, and the exterior structure is steel frame structural system. Four frame columns were set at four corners of the tower to form the frame beam of 30 meters span. Collapsible loess foundation was treated by soil compaction pile. Embedded column footing was combined with in-built steel beam in foundation platform to treat the column footing. High masonry wall was achieved by setting reinforced concrete frame in the masonry wall. The architectural intention was perfectly realized by structural design.Keywords: tower architecture; steel structure; concentrically braced steel frame structure; joint design作者简介：陈林，一级注册结构工程师，Email：snakechenlin1013@sina.com.cn。参考文献［1］GB 50025—2004 湿陷性黄土地区建筑规范［S］. 北京：中国建筑工业出版社，2004.［2］CECS 159—2004 矩形钢管混凝土结构技术规程［S］. 北京：中国计划出版社，2004.［3］ANSYS分析手册［M］.匹兹堡：美国ANSYS公司，2002.［4］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.［5］MIDAS理论手册［M］. 北京：北京迈达斯公司，2004.
