【摘要】：上海中心大厦外幕墙系统采用了分区悬挂的巨型柔性悬挂式幕墙支撑结构体系.该体系远离主体结构、几何造型扭曲、分区悬挂重量大、悬挂高度高、竖向支承刚度柔且不均匀,整个幕墙结构体系构成及传力较为特殊导致其与主体结构协同工作复杂,给结构设计带来许多前所未有的技术挑战.从方案到施工图设计过程,无论是结构体系还是节点构造均经历了多轮的反复论证分析与优化.尤其是采用整体模型协同分析,对水平和竖向荷载下幕墙支撑结构与主体结构协同工作性能、竖向地震反应、以及施工过程中幕墙支撑结构的受力特性等问题进行了深入地分析和研究.确保了工程建设的顺利实施,实际安装施工也验证了该结构设计的可靠性.上海中心幕墙支撑结构设计经历了艰辛的设计历程,其相关设计方法和成果是对现有高层建筑幕墙结构设计理念和方法的丰富和完善,同时也引发了对高层建筑复杂幕墙系统结构设计的新的思考.
[Abstract]:The outer curtain wall system of Shanghai Central Mansion adopts the giant flexible suspension curtain wall supporting structure system, which is far away from the main structure, with distorted geometry, heavy weight and high suspension height. The stiffness of vertical support is flexible and uneven, and the structure and transmission of the curtain wall structure are very special, which makes it complicated to work in coordination with the main structure, and brings many unprecedented technical challenges to the structural design, from the scheme to the design process of the construction drawing. Both the structural system and the joint structure have undergone repeated analysis and optimization of multiple rounds, especially the cooperative analysis of the whole model and the cooperative working performance of the curtain wall bracing structure and the main structure under horizontal and vertical loads. The vertical seismic response and the mechanical characteristics of curtain wall bracing structure during construction are deeply analyzed and studied to ensure the smooth implementation of engineering construction. The reliability of the structure design has also been verified by the actual installation construction. The design of the supporting structure of the central curtain wall in Shanghai has experienced a difficult design process. The related design methods and results are the enrichment and perfection of the existing concepts and methods of curtain wall structure design of high-rise buildings, and also lead to a new thinking on the structural design of complex curtain wall system of high-rise buildings.
