（中國(guó)建筑第七工程局有限公司，鄭州 450004）［摘要］大跨度高空鋼骨混凝土結(jié)構(gòu)連廊施工宜采用吊模體系。根據(jù)施工模擬原理，采用有限元分析軟件ANSYS分析了淮北礦業(yè)辦公大樓施工過程中鋼骨混凝土結(jié)構(gòu)連廊及支撐體系的應(yīng)力和變形情況，驗(yàn)證了支撐結(jié)構(gòu)的合理性，并根據(jù)分析結(jié)果，建議采取適當(dāng)?shù)拇胧┛刂破渥冃?。采用鋼懸索連接H型鋼與豎向桁架以加強(qiáng)支撐體系后，鋼骨混凝土結(jié)構(gòu)及支撐結(jié)構(gòu)施工過程最大位移與應(yīng)力值減小，保證了施工過程的質(zhì)量和安全。［關(guān)鍵詞］吊模法; 施工模擬; 應(yīng)力; 變形中圖分類號(hào)：TU375.5 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2015)05-0091-06Construction simulation analysis of large-span steel reinforced concrete corridor at high altitudeZhang Peng, Dou Guoju, Li Yonghui(China Construction Seventh Engineering Division Co., Ltd., Zhengzhou 450004, China)Abstract: Suspended form method is suitable for the construction of large-span steel reinforced concrete corridor at high altitude. According to the principle of construction simulation analysis, finite element analysis software ANSYS was used to calculate the stress and deformation of steel reinforced concrete corridor and its supporting system during the construction of Huaibei mining office building. The rationality of supporting structure was verified. Based on the analysis results, it was suggested to take the appropriate measures to control the deformation. The maximum of stress and deformation of steel reinforced concrete corridor and supporting structure during the construction were reduced after using steel suspension cable to connect H-steel beam and vertical steel truss. Thus, the quality and safety of construction were ensured.Keywords: suspended form method; staged construction analysis; stress; deformation作者簡(jiǎn)介：張鵬，博士，高級(jí)工程師，Email：zhangpengkjb@126.com。參考文獻(xiàn)［1］丁威，張寶斌．新型組合結(jié)構(gòu)鋼骨梁吊模施工技術(shù)［J］．建筑安全，2004，11(6):26-27．［2］張國(guó)勛，梁學(xué)明，花繼華．鋼骨混凝土大梁模板支撐體系設(shè)計(jì)與施工［J］．建筑技術(shù)，2007，38 (8):575-576．［3］陳安英，郭正興．鋼骨梁自承重吊掛支模施工技術(shù)［J］．施工技術(shù)，2008，37(2): 43-45．［4］劉學(xué)武，郭彥林，張慶林，等.CCTV新臺(tái)址主樓施工過程結(jié)構(gòu)內(nèi)力和變形分析［J］．工業(yè)建筑，2007，37(9):22-29.［5］GB 50666—2011混凝土結(jié)構(gòu)工程施工規(guī)范［S］.北京：中國(guó)建筑工業(yè)出版社，2012.［6］GB 50017—2003鋼結(jié)構(gòu)設(shè)計(jì)規(guī)范［S］.北京：中國(guó)計(jì)劃出版社，2003.［7］王彥超. 寧波聯(lián)盛高空鋼結(jié)構(gòu)連廊液壓同步整體提升施工分析［J］.建筑結(jié)構(gòu)，2013，43(S1):1012-1016.
