陸道淵,江蓓,王經(jīng)雨(華東建筑設(shè)計研究院有限公司,上海 200002)[摘要]天津津門酒店為地上17層的連體結(jié)構(gòu)。從地上層14開始兩個框剪結(jié)構(gòu)單體連為一體,連體部分采用了鋼桁架,桁架上下弦桿分別伸入各單體的剪力墻內(nèi)一跨,連體部分的跨度為30~35m。介紹了天津津門酒店的結(jié)構(gòu)體系、地基基礎(chǔ)等設(shè)計要點的同時,重點介紹了該連體結(jié)構(gòu)設(shè)計的主要問題和解決方法。通過彈塑性時程分析找出了工程的結(jié)構(gòu)薄弱部位,同時也驗證了結(jié)構(gòu)體系是合理的。[關(guān)鍵詞]連體結(jié)構(gòu);框剪結(jié)構(gòu);鋼桁架中圖分類號:TU398.7文獻(xiàn)標(biāo)識碼:A文章編號:1002-848X(2012)05-0096-05Structural design of Tianjin Jinmen HotelLu Daoyuan,Jiang Bei,Wang Jingyu(East China Architectural Design & Research Institute Co., Ltd., Shanghai 200002, China)Abstract: Tianjin Jinmen hotel, which is a 17 floors building, is a connective structure linked with two towers. Two frame-wall structures were linked with steel truss from floor 14. The chord of truss is inserted into walls in both sides for one span, and the span length of connecting part is about 30~35 meters. The structure system and foundation of the hotel were introduced, and the main problems and solving methods about the connected structure design were also mainly introduced. Through elasto-plasic time-history analysis, the structure’s weak position was found. At the same time, it was proved that the structure system is feasible.Keywords: connected structure; frame-wall structure; steel truss作者簡介:陸道淵,教授級高工,Email:daoyuan_lu@ecadi.com。參考文獻(xiàn)[1] JGJ 3—2002 高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程[S]. 北京:中國建筑工業(yè)出版社,2002.[2] JGJ 94—2008 建筑樁基技術(shù)規(guī)范[S]. 北京:中國建筑工業(yè)出版社,2008.[3] 郎婷,邵強,王晗. 南京徐礦明星國際商務(wù)中心結(jié)構(gòu)設(shè)計[J]. 建筑結(jié)構(gòu),2010,40(11):67-71.[4] 廖耘. 天津津門項目罕遇地震彈塑性時程分析報告[R]. 廣州:廣州數(shù)力工程顧問有限公司,2007.
