苏州东方之门刚性连体超高层结构设计

Structural design on rigid-connected twin-tower of East Gate in Suzhou

苏州东方之门为双塔、连体和带加强层及转换层的非对称复杂高层建筑结构。分析了主体结构受力体系和特点,着重介绍了连接体结构的计算分析,提出了针对考虑楼板厚度、控制双塔沉降差异、防连续性倒塌、考虑施工模拟等因素影响的设计加强措施,如加强单塔刚度和强度、连体刚度形成前的施工顺序的合理建议等。

East Gate in Suzhou is an asymmetrical complicated high-rise building which is a twin-tower structure with crossover, transferred story and strengthened story. The system and feature of the main structure were described. Analysis results of the crossover were emphatically introduced. Strengthened design measures were put forward corresponding to influence of slab thickness, the control of twin-tower subsidence differences, the prevention of the progressive collapse and the construction process simulation. These measures include improving the stiffness and strength of each tower and setting proper construction process before the form of the stiffness of crossover.
