曾濱，張明波（中冶建筑研究總院， 北京100088）［摘要］介紹了國(guó)家體育場(chǎng)中心地倉舞臺(tái)開合結(jié)構(gòu)的優(yōu)化設(shè)計(jì)過程，該結(jié)構(gòu)由主桁架行走系統(tǒng)和開合板行走系統(tǒng)這兩種獨(dú)立運(yùn)行的系統(tǒng)組成，由傳動(dòng)電控系統(tǒng)來實(shí)現(xiàn)快速開啟和閉合。地倉打開時(shí)主結(jié)構(gòu)在地倉兩側(cè)收納，形成一個(gè)完整的、可利用地下空間的智能機(jī)械舞臺(tái)；地倉閉合時(shí)體育場(chǎng)可正常進(jìn)行大型體育賽事和文化活動(dòng)，大大提高了國(guó)家體育場(chǎng)的使用效能?；诎踩?、經(jīng)濟(jì)、適用的基本原則，在滿足傳動(dòng)電控動(dòng)力要求的條件下，對(duì)各種工作狀態(tài)進(jìn)行了結(jié)構(gòu)設(shè)計(jì)優(yōu)化，為類似工程提供了設(shè)計(jì)思路。［關(guān)鍵詞］鋼結(jié)構(gòu)； 開合結(jié)構(gòu)； 舞臺(tái)中圖分類號(hào)：TU391 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：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作者簡(jiǎn)介：曾濱，博士，教授級(jí)高工，Email:zengb99@163.com。參考文獻(xiàn)［1］范重.國(guó)家體育場(chǎng)大跨度結(jié)構(gòu)設(shè)計(jì)中的關(guān)鍵技術(shù)［C］//首屆全國(guó)建筑結(jié)構(gòu)技術(shù)交流會(huì)論文集. 建筑結(jié)構(gòu)，2006，36（S1）：18-20.［2］蔣萊,鐘天朗.“鳥巢”體育旅游開發(fā)現(xiàn)狀及對(duì)策研究［C］//第九屆全國(guó)體育科學(xué)大會(huì)論文摘要匯編. 2011.［3］張風(fēng)文,劉錫良.開合屋蓋結(jié)構(gòu)行走機(jī)構(gòu)的應(yīng)用研究［J］.建筑結(jié)構(gòu),2002,32(9):29-33［4］劉錫良.現(xiàn)代空間結(jié)構(gòu)［M］.天津：天津大學(xué)出版社,2003.［5］苑輝,李杰,李清.鋼結(jié)構(gòu)設(shè)計(jì)［M］.北京:中國(guó)計(jì)劃出版社,2006.
