Abstract: Concrete-filled steel tube frame-concrete corewall structure is adopted by Qingdao Development Zone Intemational Trade Center. Through its structural analysis and design, this paper mainly introduces its structural form selection, and detail design,  plan and vertical layout, and discusses some measures for ensuring floor entirety and reinforcing joint, which put forward some constructive advices for design of frame corewall structure and remedying joint, and can supply references to similar engineering design.
Keywords: frame corewall structure, hybrid structure, high-rise steel structure, concrete-filled steel tube; steel reinforced concrete; structural form selection
