Abstract:Zhuxi Financial Center innovatively applies the steel pipe column frame-row steel pipe steel plate  corewall system, which has the advantages of high bearing capacity, light weight, fast construction speed and cost saving. Analyses of the Zhuxi Financial Center were conducted including analysis under the frequent earthquake, elastic-plastic analysis under the rare earthquake, checking calculation of bearing capacity of key components, finite element analysis on key components and so on. The analyses show that the overall index of the structure meets the specification limit value requirements. The structure has good energy consumption and high ductility. The bearing capacity in the component level meets the safety checking calculation requirements, and the structure meets the set performance target requirements. It provides engineering example references for the design and popularization of the steel pipe column frame-row steel pipe steel plate  corewall system.

Keywords:super high-rise; steel pipe frame-row steel pipe steel plate corewall; composite structure; structural energy consumption; ductility; hierarchical carrying capacity
