摘要
万达中心由坐落于4层裙楼上的南、北两栋高度和结构体系截然不同的塔楼组成。南塔楼主体结构高度195.6m,北塔楼主体结构高度147.7m。工程结构存在大底盘、多塔楼、平面和竖向不规则等多项抗震不利因素,属于复杂高层建筑结构。结构设计采用多种计算模型和计算软件进行分析,并采取有针对性的抗震加强措施。采取依塔楼刚度分配质量的模型进行分塔计算。
Wada Center is composed of one skirt building and two tower buildings with different heights and different structure systems.The south tower is 195.6 meters high and the north tower is 147.7 meters high.Some adverse factors,such as irregular plane and vertical,are existed in the complicated and high-rise building with enlarged base.Based on structural aseismic conception design,different analysis methods and seismic fortification measure were given.The principle of quality distribution by tower stiffness was applied to the calculation model of single-tower.
