（北京市建筑設(shè)計(jì)研究院有限公司， 北京 100045）［摘要］援孟加拉孟中友誼展覽中心地上部分總長(zhǎng)度為228m，總寬度為78.5m，設(shè)置兩道伸縮縫將主體結(jié)構(gòu)分為三部分，其中兩側(cè)為展廳，中間為登陸廳。展覽中心采用框架結(jié)構(gòu)體系，屋頂為空間鋼桁架。主要介紹該工程的項(xiàng)目概況、屋頂鋼桁架布置和結(jié)構(gòu)分析計(jì)算，著重闡述孟加拉當(dāng)?shù)氐卣饏?shù)的確定、特殊風(fēng)荷載的確定、鋼桁架屋頂采取的抗風(fēng)吸措施，以及桁架下分叉柱節(jié)點(diǎn)設(shè)計(jì)等，并介紹了設(shè)計(jì)中關(guān)于場(chǎng)址選擇、建筑材料選用等其他關(guān)鍵問(wèn)題。［關(guān)鍵詞］鋼桁架; 地震參數(shù); 特殊風(fēng)荷載; 分叉柱; 援外項(xiàng)目中圖分類(lèi)號(hào)：TU318 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2014)20-0105-04Structural design of Sino-Bangladesh Friendship Exhibition CentreLiang Congzhong, Wang Rongfang, Zhao Boyao（Beijing Institute of Architectural Design, Beijing 100045, China）Abstract: The total size of aboveground part of Sino-Bangladesh Friendship Exhibition Centre is 228m in length and 78.5m in width. The main structure, which is divided into three parts by two expand joints, consists of two exhibition halls located on both sides and a landing hall located in the middle. This building adopts frame structural system and the roof adopts spatial steel truss. The overview of this project was introduced as well as the layout of steel truss roof and structural analysis. The identification of local seismic parameters in Bangladesh was focused on as well as the identification of special wind loads, wind resistance measures for steel truss roof, and bifurcated column node design under the truss. Some other key issues during the design process were also introduced, such as site selection, construction materials selection and so on.Keywords: steel truss; seismic parameter; special wind load; bifurcated column; aiding project作者簡(jiǎn)介：梁叢中，碩士，高級(jí)工程師，Email:liangcongzhong@biad.net.cn。參考文獻(xiàn)［1］GB 50011—2010 建筑抗震設(shè)計(jì)規(guī)范［S］.北京：中國(guó)建筑工業(yè)出版社，2010.［2］BNBC-2006 Bangladesh building code［S］.Bangladesh：BNBC, 2006.［3］ASCE/SEI 7-05 Minimum design loads for buildings and other structures［S］.
