Structural Design of Jinyulan Square Hotel/Fu Jinshen, Zhang Fulin(East China Architectural Design & Research Institute Co., Ltd., Shanghai 200002,China)
Abstract:Jinyulan square hotel is a super highrise building of 52 stories. The structural system below the 48th story is RC framecorewall structure，above the 48th story is steel framecorewall ，and the total hight is 226m。According to the requirement of the unit in charge of the building who asked to add 3 stories and 144m high for business use when the construction was in the 34th floor, the top megaframe of steel is 40m. In view of the character of the project and the acute great change, the structural design is presented and several related problems such as structural scheme, linear and nonlinear analysis, the design of the top megaframe of steel, translationfloor, joints which connecting steel rein formed concrete, steel frame and spatial hinged column footing are discussed.
