張同億,肖自強(qiáng),李亮,張銳,羅斌,張建明(中國中元國際工程公司,北京 100089)[摘要]北京財富中心二期公寓樓結(jié)構(gòu)高度194m,采用框架核心筒型鋼混凝土混合結(jié)構(gòu)體系。介紹了結(jié)構(gòu)體系及布置、結(jié)構(gòu)設(shè)計思路、抗震設(shè)防性能化目標(biāo)、結(jié)構(gòu)整體計算分析結(jié)果等。特別給出地基基礎(chǔ)沉降分析、轉(zhuǎn)換結(jié)構(gòu)體系比選及轉(zhuǎn)換塊結(jié)構(gòu)有限元分析、平面外伸部分子結(jié)構(gòu)分析、外框承擔(dān)剪力分析等專項分析內(nèi)容及方法。最后探討了混合結(jié)構(gòu)在高烈度地區(qū)超高層建筑中的適用性及建議。[關(guān)鍵詞]混合結(jié)構(gòu); 高層建筑; 結(jié)構(gòu)分析; 轉(zhuǎn)換結(jié)構(gòu)中圖分類號:TU318.2 文獻(xiàn)標(biāo)識碼:A 文章編號:1002-848X(2013)03-0059-04Structural design on apartment tower of Fortune Center phaseⅡin BeijingZhang Tongyi, Xiao Ziqiang, Li Liang, Zhang Rui, Luo Bin, Zhang Jianming(China IPPR International Engineering Corporation, Beijing 100089, China)Abstract: The tall apartment building of Fortune Center phaseⅡ in Beijing is 194m height, and mixed frame-corewall structure is adopted. The structure system and arrangement, some structural design ideas, performance-base seismic objectives and structure calculation analysis results were provided. Some special analysis methods and contents were given such as foundation settlement analysis, transformation structure system election and finite element analysis on conversion block structure, overhang substructure analysis, out-frame shear force analysis, etc. Finally the applicability and suggestions were discussed for the application of tall mixed structure in high intensity area.Keywords: mixed structure; tall building; structural analysis; transformation structure作者簡介:張同億,博士,教授級高級工程師,Email: zhangtongyi@ippr.net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]GB 50011—2001 建筑抗震設(shè)計規(guī)范[S]. 北京:中國建筑工業(yè)出版社,2001.[3]徐培福,薛彥濤,肖從真,等. 高層型鋼混凝土框筒混合結(jié)構(gòu)抗震性能試驗研究[J].建筑結(jié)構(gòu), 2005,35(5):3-8.[4]徐培福,戴國瑩.超限高層建筑結(jié)構(gòu)基于性能抗震設(shè)計的研究[J]. 土木工程學(xué)報,2005,38(1):3-10.[5]黃吉鋒,李云貴,邵弘,等.考慮彈塑性內(nèi)力重分配的框剪結(jié)構(gòu)等剪應(yīng)力調(diào)整[J]. 建筑科學(xué),2005,21(3):3-9.
