曾滨，张明波（中冶建筑研究总院， 北京100088）［摘要］介绍了国家体育场中心地仓舞台开合结构的优化设计过程，该结构由主桁架行走系统和开合板行走系统这两种独立运行的系统组成，由传动电控系统来实现快速开启和闭合。地仓打开时主结构在地仓两侧收纳，形成一个完整的、可利用地下空间的智能机械舞台；地仓闭合时体育场可正常进行大型体育赛事和文化活动，大大提高了国家体育场的使用效能。基于安全、经济、适用的基本原则，在满足传动电控动力要求的条件下，对各种工作状态进行了结构设计优化，为类似工程提供了设计思路。［关键词］钢结构； 开合结构； 舞台中图分类号：TU391 文献标识码：A 文章编号：1002-848X(2013)19-0074-04Optimization design of retractable stage in Center National StadiumZeng Bin, Zhang Mingbo（Building Research Institute of China Metallurgical Group, Beijing 100088, China）Abstract: The design and optimization of retractable stage in Center National Stadium was described. The retractable stage consisted of main moving trusses and composites plates, which could be driven by electric control system and opened or closed quickly. When the stage was opened, the trusses and plates were parked in both sides and a big underground space could be owned. When the stage was closed, a platform with trusses and plates was presented, where the major sporting events and cultural events could be held in. For security, economy, applicable principles, the retractable stage was carried out by considering many working cases, and provided design ideas for similar projects.Keywords: steel structure; retractable structure; stage作者简介：曾滨，博士，教授级高工，Email:zengb99@163.com。参考文献［1］范重.国家体育场大跨度结构设计中的关键技术［C］//首届全国建筑结构技术交流会论文集. 建筑结构，2006，36（S1）：18-20.［2］蒋莱,钟天朗.“鸟巢”体育旅游开发现状及对策研究［C］//第九届全国体育科学大会论文摘要汇编. 2011.［3］张风文,刘锡良.开合屋盖结构行走机构的应用研究［J］.建筑结构,2002,32(9):29-33［4］刘锡良.现代空间结构［M］.天津：天津大学出版社,2003.［5］苑辉,李杰,李清.钢结构设计［M］.北京:中国计划出版社,2006.
