Due to the special requirements in manufactory functions, there are no rigid slabs at middle floors other than the roof. Accordingly, solutions to these difficulties are proposed in the building design. Steel structure design is briefly described in this paper, including design parameters, structure arrangement, analysis model and results discussion.
Keywords: huge one-bay structure,frame-brace system,transformation truss,high-rise steel structure
