[摘要]南京祿口國際機(jī)場交通中心工程結(jié)構(gòu)平面狹長,抗扭剛度很弱;局部樓層層高相差極大,容易形成極弱的薄弱層;設(shè)備層存在較多轉(zhuǎn)換大梁;標(biāo)準(zhǔn)層樓面有較大開洞,形成兩排單跨框架結(jié)構(gòu)等。針對工程結(jié)構(gòu)特點,結(jié)合抗震規(guī)范要求,提出了若干適當(dāng)技術(shù)措施,使主體結(jié)構(gòu)具有較好的承載和變形能力;并對主體結(jié)構(gòu)進(jìn)行了詳細(xì)的彈性和彈塑性分析,找出結(jié)構(gòu)潛在薄弱環(huán)節(jié),為工程設(shè)計提供參考;最后介紹了結(jié)構(gòu)的關(guān)鍵部位設(shè)計。[關(guān)鍵詞]結(jié)構(gòu)設(shè)計;型鋼轉(zhuǎn)換梁;屈曲約束支撐;單跨框架結(jié)構(gòu);彈塑性時程分析;抗震性能;弦支穹頂中圖分類號:TU318-2文獻(xiàn)標(biāo)識碼:A文章編號:1002-848X(2012)05-0135-05Structural design of Nanjing Lukou International Airport Transportation CenterTao Xianghua (East China Architectural Design & Research Institute Co., Ltd., Shanghai 200002, China)Abstract: Nanjing Lukou International Airport Transportation Center is a high-rise building with the following structural features:narrow and long floor plan, weak torsional rigidity; large floor-to-floor height difference, which in turn will form weak story; lots of transfer girders at the mechanical floor; large openings at typical floors, forming two rows of single span frames, etc. Considering structural features and seismic codes, number of technical measures were proposed in order to increase the structural bearing and deforming capacity. Elastic and elasto-plastic analysis were performed for the main structure in order to identify the potential weakness of the structure and provide insight information for the design. In addition, design of key structural members was reviewed in emphasis as well.Keywords: structural design; SRC transfer girder; buckling restrained brace; single span frame; elasto-plastic time-history analysis; aseismic performance; suspen-dome作者簡介:陶湘華,碩士,一級注冊結(jié)構(gòu)工程師,Email:xianghua_tao@ecadi.com。參考文獻(xiàn)[1]南京祿口國際機(jī)場二期建設(shè)工程交通中心及附屬建筑物巖土工程勘察報告[R]. 南京:江蘇省交通規(guī)劃設(shè)計院股份有限公司, 2011.[2]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.[3]JGJ 61—2007 空間網(wǎng)格結(jié)構(gòu)設(shè)計規(guī)程[S]. 北京:中國建筑工業(yè)出版社,2007.[4]孟美莉,吳兵,傅學(xué)怡,等. 第26屆世界大學(xué)生運(yùn)動會籃球館弦支穹頂屋蓋結(jié)構(gòu)設(shè)計[J]. 建筑結(jié)構(gòu),2011,41(4):24-28,10.
