吳任鵬1，朱立剛2，魏強1(1 山東同圓設(shè)計集團，濟南 250000；2 奧雅納工程咨詢（上海）有限公司，上海 200031)［摘要］通過研究加強層的工作機理，并結(jié)合一個超高層結(jié)構(gòu)的實例，研究和分析了帶加強層結(jié)構(gòu)的位移角、內(nèi)外筒剪力、傾覆力矩的分配、薄弱層等基本參數(shù)。結(jié)果表明，加強層能明顯提高結(jié)構(gòu)剛度和抗傾覆能力，減小結(jié)構(gòu)位移，但易使加強層的下一層形成薄弱層。最后，給出了加強層抗震構(gòu)造措施。［關(guān)鍵詞］加強層; 核心筒; 薄弱層; 抗震構(gòu)造措施中圖分類號：TU398.2 文獻標(biāo)識碼：A 文章編號：1002-848X(2013)01-0010-04Seismic behavior analysis and design of strengthened storey in a super high-rise buildingWu Renpeng1, Zhu Ligang2, Wei Qiang1（1 Shandong Tongyuan Design Group Co., Ltd., Jinan 250000, China; 2 Arup International Consultants(Shanghai) Co., Ltd., Shanghai 200031, China）Abstract: The working mechanism of strengthened storey was studied. Combined with an engineering example, the basic parameters, such as storey drift, storey shear and overturn moment distributed in-out core wall, weak layer and so on, were studied and analyzed. The results show that the strengthened storey can increase the stiffness of the structure, anti-overturning moment and decrease displacement of the structure. But the storey below the strengthened one is easy to be weak. Finally, the details of seismic design in the strengthened storey were listed.Keywords: strengthened storey; core wall; weak layer; seismic design detail作者簡介：吳任鵬，一級注冊結(jié)構(gòu)工程師，Email：wurpedu@163.com參考文獻［1］劉大海，楊翠如.高層建筑結(jié)構(gòu)方案優(yōu)選［M］. 北京：中國建筑工業(yè)出版社，1996.［2］徐培福，傅學(xué)怡，王翠坤，等.復(fù)雜高層建筑結(jié)構(gòu)設(shè)計［M］. 北京：中國建筑工業(yè)出版社，2005.［3］JGJ 3-2010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，2011.
