In order to achieve the large cantilever and long span demand of architectural presentation, a relatively complicated structure form, that is the steel-tube concrete column-folded network, has been adopted for the roof. During the structural design procedure, various load combinations have been analyzed, and the deformation and stress distribution of the structure have been checked. In addition, elastic design analysis under intermediate earthquake and Pushover analysis have been conducted for the structure. The analysis results show that the structural system is safe and reliable and has a good seismic performance.Keywords: long-span network structure; structure design; temperature action; seismic action; Pushover analysis作者簡介:柳美玉, 碩士, 一級注冊結(jié)構(gòu)工程師, Email: liumeiyu@ippr.net參考文獻[1]李云,張同億,張春俊,等. 石家莊國際會展中心中央大廳結(jié)構(gòu)設(shè)計[J]. 建筑結(jié)構(gòu),2013, 43(3):21-25.[2]徐承強,曲曉寧. 正放抽空四角錐網(wǎng)架設(shè)計[J]. 建筑結(jié)構(gòu),2011,41 (S2): 69-70.[3]JGJ 7—2010 空間網(wǎng)格結(jié)構(gòu)技術(shù)規(guī)程[S]. 北京: 中國建筑工業(yè)出版社, 2010.[4]盧旦, 李承銘, 田煒. 某復(fù)雜鋼結(jié)構(gòu)網(wǎng)架設(shè)計[J]. 工程設(shè)計,2007(12): 31-35.[5]丁蕓孫, 朱坊云. 網(wǎng)架設(shè)計中常見技術(shù)問題的探討(上) [J]. 空間結(jié)構(gòu),1996,2(3): 32-36.[6]GB 50011—2010 建筑抗震設(shè)計規(guī)范[S].北京: 中國建筑工業(yè)出版社,2010.[7]石家莊國際會展中心風(fēng)荷載及風(fēng)振研究報告[R]. 石家莊:石家莊鐵道大學(xué)風(fēng)工程研究中心,2012.[8]GB 50009—2001 建筑結(jié)構(gòu)荷載規(guī)范[S]. 2006年版.北京: 中國建筑工業(yè)出版社,2006.
