［摘要］宁波市商会·国贸中心由A，B两幢塔楼和裙房组成，塔楼A高度207.0m，塔顶为层层内收的莲花瓣造型。工程结构存在大底盘、多塔楼、平面及竖向不规则和高位转换等多项不利因素，属于复杂高层建筑结构。结构设计时从抗震概念设计出发，采用多种计算方法进行分析，并采取有针对性的抗震加强措施。重点介绍了塔楼A结构的超限分析和抗震处理措施。

Liu 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
