Structural Design of Nanjing Greenland Zifeng Mansion Super Highrise Building/Yan Feng, Zhou Jianlong, Wang Dasui, Zheng Li, Lang Ting (East China Architectural Design & Research Institute Co., Ltd., Shanghai 200002,China)
Abstract:The Nanjing Greenland Zifeng Mansion is a super high structure,of which roof height is 381 meter. It adopted builtin rock pile foundation and the maximal thickness of soleplate is 34 meter. The structural system of the mansion is framecorewall with outriggers and belt members. It was introduced for rudimental calculating result such as mode, displacement responses under horizontal actions. Some exceptive problems such as outriggers and belt members, transfer columns, construction sequence analysis, vertical deformation difference, elastic and plastic analysis are discussed.
