張達生，楊競，賀誠（中信建筑設計研究總院有限公司，武漢 430014）［摘要］中華城A棟為一棟涉及多種業(yè)態(tài)的超高層建筑，復雜的建筑功能導致建筑結(jié)構(gòu)多項規(guī)則性指標超限，設計針對建筑結(jié)構(gòu)的超限情況采取相應處理措施，較好地解決建筑功能與結(jié)構(gòu)規(guī)則性之間的矛盾。采用基于性能的設計方法進行超限高層的抗震設計，實現(xiàn)“小震不壞，中震可修，大震不倒”三水準抗震設防目標。［關(guān)鍵詞］超限高層；結(jié)構(gòu)體系；性能目標；延性；靜力彈塑性中圖分類號：TU398文獻標識碼：A文章編號：1002-848X(2012)09-0035-04Structure design of an out-of-codes high-rise building in Chinese CityZhang Dasheng, Yang Jing, He Cheng(CITIC General Institute of Architectural Design and Research Co., Ltd., Wuhan 430014, China)Abstract: The building A in Chinese City project is an out-of-codes high-rise building with a variety of formats, and the complex architectural function leads to a number of structural regularity indexes out-of-codes. According to this situation, reasonable treatment measures were taken during structure design, and the contradiction between architectural function and structural indexes was solved. Performance-based design method was used in structural seismic design of the building A. The results show that the structure system can meet the requirements of no-damage under light earthquake, repairable under medium earthquake, and no-collapse under strong earthquake.Keywords: out-of-codes high-rise building； structure system； performance objective； ductility； static elastic-plastic作者簡介：張達生，教授級高級工程師，一級注冊結(jié)構(gòu)工程師，Email:zzhangdasheng@163.com。參考文獻［1］徐培福，傅學怡，王翠坤，等.復雜高層建筑結(jié)構(gòu)設計［M］.北京：中國建筑工業(yè)出版社，2005.［2］中華城工程場地地震安全性評價報告［R］.武漢：武漢地震工程研究院，2009.［3］GB 50011—2001建筑抗震設計規(guī)范［S］.2008年版.北京：中國建筑工業(yè)出版社，2008.
