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。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.
