(同濟大學建筑設計研究院，上海 200092)［摘要］寧波市商會·國貿(mào)中心由A，B兩幢塔樓和裙房組成，塔樓A高度207.0m，塔頂為層層內(nèi)收的蓮花瓣造型。工程結(jié)構(gòu)存在大底盤、多塔樓、平面及豎向不規(guī)則和高位轉(zhuǎn)換等多項不利因素，屬于復雜高層建筑結(jié)構(gòu)。結(jié)構(gòu)設計時從抗震概念設計出發(fā)，采用多種計算方法進行分析，并采取有針對性的抗震加強措施。重點介紹了塔樓A結(jié)構(gòu)的超限分析和抗震處理措施。［關鍵詞］大底盤；多塔樓；超限；平面不規(guī)則；豎向不規(guī)則；概念設計Structural Design of Ningbo’s Commercial and International Trade Center BuildingLiu Chuanping,Zhang Zhibin(Architectural Design & Research Institute of Tongji University,Shanghai 200092,China)Abstract:Ningbo’s commercial and international trade center building is composed by one skirt building and two tower buildings with A and B,the height of A tower is 207 meters. Some of adverse factors,such as plane and vertical irregular and high transfer story etc,are existed in the complicated and high-rise building with large podium. Based on structural aseismic conception design,different analysis methods and seismic fortification measures are given. And moreover,the analysis beyond code limits of A tower building and seismic fortification measures are introduced in detail.Keywords:large podium; multi-tower building; beyond code limits; plane irregular; vertical irregular; conception design作者簡介：劉傳平(1966-)，男，學士，高級工程師，E-mail:liuchuanping@126.com。參考文獻［1］高立人，方鄂華，錢稼茹. 高層建筑結(jié)構(gòu)概念設計［M］.北京：中國計劃出版社，2005.［2］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.［3］高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程(JGJ3—2002)［S］.北京：中國建筑工業(yè)出版社，2002.
