Abstract:Nanjing Suning Ruicheng Phase II office building is a 42-floor super high-rise building with 3 underground floors. The upper structure of the building adopts the frame-corewall structural system, and the bottom frame columns adopt steel reinforced concrete columns. The structural design method and process of the office building were introduced, including the determination of structural performance design goals, calculation and analysis, etc. Aiming at the out-of-code conditions of the structure of this project and the difficulties of the bifurcated columns, several analyses were conducted on the structure including elastic response spectrum analysis under the frequent earthquake, elastic time-history analysis under the frequent earthquake, non-yielding checking calculation under the fortification earthquake, elastic checking calculation under the fortification earthquake, and dynamic elastoplastic time-history analysis under the rare earthquake. The calculation results show that the structural design is safe, reliable, economical and reasonable.

Keywords:super high-rise building; performance design goal; bifurcated column; strengthened story; time-history analysis
