（北京市建筑設(shè)計(jì)研究院有限公司， 北京 100045）［摘要］詳細(xì)介紹了青島北站主站房屋蓋鋼結(jié)構(gòu)的體系和成形過程、構(gòu)件截面、設(shè)計(jì)荷載與作用、設(shè)計(jì)標(biāo)準(zhǔn)、分析模型和關(guān)鍵節(jié)點(diǎn)設(shè)計(jì)；研究了屋蓋結(jié)構(gòu)的靜力和動(dòng)力性能、屋蓋結(jié)構(gòu)的整體穩(wěn)定性和局部穩(wěn)定性及預(yù)應(yīng)力壓桿的極限承載能力；對(duì)承重索和抗風(fēng)索的預(yù)應(yīng)力進(jìn)行了優(yōu)化分析，有效降低了立體拱架主拱內(nèi)的彎矩峰值；運(yùn)用現(xiàn)行規(guī)范公式對(duì)異形截面進(jìn)行了強(qiáng)度和穩(wěn)定性驗(yàn)算，證明了其可行性。［關(guān)鍵詞］火車站站房; 預(yù)應(yīng)力空間結(jié)構(gòu); 立體拱架; 預(yù)應(yīng)力壓桿; 異形截面; 節(jié)點(diǎn)設(shè)計(jì)中圖分類號(hào)：TU393.3文獻(xiàn)標(biāo)識(shí)碼：A文章編號(hào)：1002-848X(2013)23-0007-07Steel structural design on main station roof of Qingdao North Railway StationZhang Xiangyong, Li Liming, Gan Ming（Beijing Institute of Architectural Design, Beijing 100045, China)Abstract: The structural system and construction process of main station roof of Qingdao North Railway Station were introduced in detail as well as the member section, design loads and effects, design standards, analysis models and the design of key joints. Static and dynamic performances of the steel roof were studied as well as the overall stability and local stability of the steel roof and ultimate bearing capacity of prestressed struts. The prestress of the wind load-bearing cable and dead load-bearing cable were optimized to effectively reduce the peak moment value within the main arch. The strength and stability of abnormal sections were checked using existing specification formula to prove their feasibility.Keywords: railway station building; prestressed spatial structure; dimensional arch; prestressed strut; abnormal section; joint design作者簡介：張相勇，博士，高級(jí)工程師，一級(jí)注冊(cè)結(jié)構(gòu)工程師，注冊(cè)咨詢工程師（投資），Email：yongzx@126.com。參考文獻(xiàn)［1］張相勇, 李黎明, 魏建友,等. 青島北站結(jié)構(gòu)設(shè)計(jì)綜述［J］. 建筑結(jié)構(gòu), 2013,43(23):1-6,13.［2］趙鵬飛, 陽升, 楊惠東,等. 青島北站站房屋蓋結(jié)構(gòu)體系研究［J］. 建筑結(jié)構(gòu)學(xué)報(bào), 2011,32(8):10-17.［3］GRAHAM H POWELL.
