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 Chamber of Commerce and International Trade Center consists of A and B towers and podiums. Tower A has a height of 207.0m. The top of the tower is a layer of lotus petals admired in layers. The engineering structure has many unfavorable factors such as large chassis, multiple towers, planes and vertical irregularities, and high-level conversions. It belongs to a complex high-rise building structure. The structural design starts from the concept design of earthquake resistance, uses a variety of calculation methods for analysis, and adopts targeted seismic strengthening measures. Highlighted the analysis of tower A structure and its anti-seismic treatment measures.
